The TE 77 High Frequency Friction Machine is a versatile reciprocating tribometer with a maximum stroke of 25 mm and maximum load of 1,000 N. It is now a well-established research and development tool for evaluation of lubricants, materials, coatings and surface treatments.
With the TE 77, sliding contact conditions can be matched to a number of machine elements. Specimens may either be of a standard format, or cut from real components, preserving surface finish and other properties.
The TE 77 was used for the inter laboratory tests for the development of ASTM G 133 “Standard Test Method for Linearly Reciprocating Ball on Flat Sliding Wear”, which addresses the dry and lubricated wear of ceramics, metals and ceramic composites and also for ASTM G 181 “Standard Practice for Conducting Friction Tests of Piston Ring and Cylinder Liner Materials Under Lubricated Conditions”.
Although not included in the inter laboratory test programs, the TE 77, in conjunction with selected adapters, can also accommodate tests specimens and provide test conditions as specified in the following standards:
ASTM D 5706 “Standard Test Method for Determining Extreme Pressure Properties of Lubricating Grease Using a High Frequency Linear-Oscillating Test Machine”
ASTM D 5707 “Standard Test Method for Measuring Friction and Wear Properties of Lubricating Grease Using a High Frequency Linear-Oscillating Test Machine”
ISO/DIN 12156-2 “Diesel Fuel Lubricity – Performance Requirement Test Method for Assessing Fuel Lubricity”
ASTM D 6079 “Standard Test Method for Evaluating Lubricity of Diesel Fuels by the High-Frequency Reciprocating Rig (HFRR)”
A large body of technical publications from existing users provides information on a wide range of non-standard research and development test procedures.
TE 77 High Frequency Friction Machine is supplied with its own floor standing bench and with integral control unit, providing sequence programmable control of load, frequency and temperature plus data acquisition of measured parameters, at both low and high speed.
The moving specimen is mounted in a carrier. A number of different geometries can be accommodated by using a range of simple clamping fixtures.
6 mm ball carrier in standard sleeve
10 mm ball carrier
6 mm diameter line contact tooling
Self aligning area contact tooling
The specimen is oscillated mechanically against the fixed lower specimen. The mechanical drive comprises a motor driven cam and scotch yoke assembly, providing pure sinusoidal motion. The drive mechanism runs inside an oil bath.
The stroke length is altered manually by adjusting splined eccentric cams on an splined eccentric shaft. Two fixed cams are provided as standard allowing strokes to be set from 0 to 12.5 mm and 12.5 mm to 25 mm, with a total of eleven discrete positions per cam. A continuously variable double cam arrangement is included, which allows continuous variation of the stroke in the range 0 to 12.5 mm.
The moving specimen is loaded against the fixed specimen through a lever mechanism actuated by a geared servomotor with in-line spring. The normal force is transmitted directly onto the moving specimen by means of the needle roller cam follower on the carrier head and the running plate on a loading stirrup. A strain gauge transducer is mounted on the lever at a point directly beneath the contact and this measures the applied load.
The fixed specimen is located in a stainless steel reservoir. The reservoir is clamped to a block that is heated by four electrical resistance elements and the temperature is monitored by a thermocouple pressed against the side of the specimen or holder. The reservoir can be moved sideways on the heater block so that multiple tests can be performed on one fixed specimen.
The heater block is mounted on flexures, which are stiff in the vertical (loading) direction, but offer limited resistance to horizontal forces. Movement in the horizontal direction is resisted by a piezo-electric force transducer, which measures the friction forces in the oscillating contact.
Special inserts are available for mounting the ISO Fuel Lubricity Test specimens and other standard specimens.
The piezo electric transducer used to measure the friction force has a sensitivity of typically 43.5 pC/N and the output range is set to match expected friction levels in the contact. The maximum friction level is +/- 500 N.
A charge amplifier converts the measured force to a proportional voltage. This is followed by a low pass filter, which fixes the upper cut off frequency of the measuring system. This serves to suppress transducer resonance. Final scaling of the signal for voltage output takes place in a second stage amplifier.
During higher frequency (>1Hz) operation, the charge amplifier is operated a.c. coupled. This eliminates the effects of d.c. signal drift over long time periods. The signal is passed through a true rms/dc converter amplifier and the final output is the true mean friction force. The instantaneous friction signal may also be logged in bursts using the integral high speed data acquisition interface.
For low frequency sliding (<1Hz), stick-slip, single pass sliding, work with the Energy Pulse Slide/Roll Adapter and also for calibration of the transducer, the charge amplifier is operated in Quasi-static d.c. coupled mode. This gives signal decay times of up to 100,000s, sufficiently long when compared to typical measurement time scales for the zero not to have moved significantly during the measurement.
Electrical Contact Resistance Measurement
The moving specimen carrier is electrically isolated from the drive shaft and therefore from the fixed specimen. This allows a millivolt potential to be applied across the contact using a Lunn-Furey Electrical Contact Resistance Circuit. The voltage signal is taken to a true rms/dc converter amplifier to give a time-smoothed average of the contact potential.
Variations in this voltage are indicative of the level of metallic contact, provided that both test specimens are conductors of electricity. This measurement may be used for observing the formation of chemical films from anti-wear and extreme pressure lubricants, the breakdown of non-conducting layers and coatings or the build-up of oxides.
The instantaneous value of contact potential is also available for data logging as high speed data.
Many wear processes are driven by temperature, be they the formation of oxides on the surfaces, the transformation of microstructure, the formation or break-down of lubricant additive or other tribochemical films, the melting of the surface (the PV limit of the material) or thermal stress induced failure.
To be more specific wear occurs as the result of the dissipation of frictional energy in the contact and this is irresistibly accompanied by a rise in temperature. The frictional energy is generated by the combination of load and sliding speed and its distribution and dissipation is influenced by other contacting conditions such as size and relative velocity.
In the reciprocating contact of the TE 77, sliding velocities are deliberately maintained at low levels in order to minimise frictional heating and, in the case of lubricated tests, to promote boundary lubrication. Minimisation of frictional heating means that contact temperature can be controlled effectively by controlling the bulk temperature of the fixed specimen. The temperature is measured with a thermocouple pressed against the fixed specimen and control is by software PID with PWM output.
This is not directly monitored on the TE 77 and assessments are made from wear scar sizes on the moving specimen and wear volumes on the stationary specimen. Specimen sizes are small enough to be placed in SEM and other surface analysis equipment for detailed chemical analysis of surface films.
With the optional TE 77/WEAR fitted, a continuous record can be made of the movement of the moving specimen relative to the fixed specimen. This measurement can be used as an indication of the combined wear of both surfaces and for identifying wear transitions.
With the optional TE 77/PROFILE system, periodic in situ profilometer measurement of the fixed specimen plate surface can be made, as an indication of wear progression.
Control and Data Acquisition
Control and data acquisition are implemented via host PC running COMPEND 2020 Windows compatible software, in conjunction with a Phoenix Tribology USB micro-controller interface.
Automatic control is implemented via user programmable test sequences. Manual control is implemented using on screen toggles. Data is stored to hard disc in either .csv or .tsv file formats.
Low Speed Data
Analogue input channels are sampled and data logged at a maximum rate of ten samples per second. Time smoothing and averaging functions are provided by hardware and software.
The standard (low data rate) r.m.s. friction signal is generated by passing the input voltage through a true r.m.s. to d.c. converter. This produces a time smoothed r.m.s. value of the friction force, integrated over a period of just over 1 second. Because the friction force signal approximates to a square wave, the r.m.s. friction signal can be considered as an average friction force as measured over at least one complete cycle, assuming a reciprocating frequency greater than 1 Hz.
By rectifying the instantaneous friction force signal and subtracting the r.m.s. average, a resulting signal corresponding to the perturbations (friction noise) can be produced. If this signal is subsequently passed through a second true r.m.s. to d.c. converter, an r.m.s. signal of friction noise can be generated. This can be used, in real time, as an analogue measure of the friction noise, hence the orderliness or otherwise of the friction signal. By dividing the r.m.s. friction noise value by the r.m.s. friction signal value, a percentage friction noise value (as a derived channel in software) can be generated.
High Speed Data
The high speed data acquisition interface provides programmable burst data acquisition of friction, contact potential and stroke position. It is implemented by means of a 16-bit six channel multi-function ADC USB card, with programmable data acquisition rates up to 50 kHz.
Data is buffered and stored direct to hard disc with a separate file automatically created for each acquisition cycle. The high speed data file names are automatically inserted as hyperlinks in the standard machine data file so that the high speed data may be viewed at the relevant place in the test.
Comparisons and Advantages
The maximum frequency on the TE 77 is 50 Hz. It should be noted that the majority of standards relating to reciprocating tribometers call for a test frequency of 50 Hz or less. The frequency range of competing electro-magnetic oscillator driven reciprocating tribometers is often higher (up to 500 Hz), but the amplitude range is lower than the TE 77, with a maximum stroke range typically up to 4 mm (but not over the full frequency range).
This is compared with 25 mm on the standard TE 77. The TE 77 will run at 50 Hz at 5 mm and 30 Hz at 15 mm stroke.
Whereas stroke length has no great significance for basic tests to evaluate the frictional and chemical film forming behaviour of lubricants, stroke length, hence sliding distance, are of great importance when it comes to wear generation. A stroke length of 10 mm is also specified in ASTM G 133.
Generation of Wear
Wear is a direct function of sliding distance, hence, the rate of generation of wear is a direct function of the rate of accumulation of sliding distance.
25 mm Stroke at 20 Hz: 60 m per minute (TE 77)
15 mm Stroke at 30 Hz: 54 m per minute (TE 77)
5 mm Stroke at 50 Hz: 30 m per minute (TE 77)
4 mm Stroke at 50 Hz: 24 m per minute (Typical electro magnetic machine performance)
1 mm Stroke at 100 Hz: 12 m per minute (Typical electro magnetic machine performance)
The longer stroke capability of the TE 77 makes it a more effective wear generator than short stroke electro magnetically driven devices. It also allows tests to be performed using variable contact width, hence variable contact pressure, curved edge fixed specimens.
Entrainment and Wear Debris
The ability of the moving specimen to “expose” all parts of the fixed specimen depends on the contact length being not more than half the stroke length. In other words, in the case of other devices, with a contact length greater than 2 mm and a maximum stroke of 4 mm, it is apparent that the centre portion of the fixed specimen will be in continuous contact with part of the moving specimen. This has serious implications for lubricant entrainment, for surface activation and for the discharge of wear debris from the contact. Debris can become entrapped and generate an unwanted third body wear mechanism. Because of this, the devices are not entirely satisfactory for adhesive wear tests with area contact specimens.
An important issue with regard to contact scale is how the wear is shared between the two contacting surfaces. Wear is a function of sliding distance. In the case of the moving specimen, the sliding distance is twice the stroke length x number of cycles. For a point on the fixed specimen, the linear wear is twice the contact length x number of cycles. In other words, the wear of the moving specimen is dependent on total sliding distance but the wear on the fixed specimen is dependent on the number of passes and the contact length. It follows that the ratio of wear between the two surfaces depends on both stroke and contact length. In order to model a real tribological contact, this contact scale parameter should be correctly modelled.
To get the model right, the contact length must be correctly scaled. Hence, running at 25 mm stroke modelling a contact length of 3 mm in an engine with 100 mm stroke, the ring specimen in the test machine should have a contact length of 0.75 mm. To model this at shorter stroke lengths would require a contact length of 0.09 mm, which is not practical.
The extra stroke length on the TE 77 means that quite a variety of large sliding specimens can be accommodated. This is particularly useful when working with test specimens cut from machine components. The test area is highly accessible and open to design of specialised specimen carriers.
Very Low Frequencies
The TE 77 offers, by means of simple interchangeable gearboxes, a minimum frequency down to 0.01 Hz. Electro magnetically driven devices typically offer a minimum operating frequency of 1 Hz. This lower end speed range allows the TE 77 machine to be used for investigating stick-slip and friction-velocity (Stribeck) curve characteristics of lubricants and materials.
TE 77/SRC Adjustable Radius Piston Ring Clamp
The reciprocating shaft has a hollow bore and connection for an oil feed. The bore communicates via oil-ways in the bush and clamp components to small jets either side of the ring sample. This allows lubricant to be added in small volumes to either side of the ring sample.
A larger clamp has been designed to accommodate rings up to 200 mm diameter. Use of this sized ring requires modification of the lubricant bath to reduce the side wall height.
TE 77/TRC Adjustable Radius Twin Piston Ring Clamp
TE 77/PT Pin on Twin Test Bath
The pin on twin test bath allows tests to be performed with a self-locating crossed cylinder geometry. This is a technique originally developed by Dr Peter Blau at Oakridge National Laboratories.
TE 77/WEAR On-Line Wear Monitoring System
TE 77/WEAR is a high-resolution capacitance proximity measuring system. Output from the device is in the form of a DC voltage proportional to displacement, suitable for data acquisition on a PC.
A capacitance non-contact probe is mounted in the moving specimen carrier. The probe is mounted approximately 0.5 mm away from a reference surface mounted on the edge of the specimen bath. The capacitance of the gap is converted to a dc voltage by a charge amplifier. The voltage is passed through a true rms/dc converter to provide the mean gap value over the length of the stroke.
The variations in the gap due to wear, lubricant film formation, thermal expansion or a combination of these are picked up by the system. The fact that the gap is small ensures that temperature effects are limited to the thermal expansion over that length.
The measuring resolution is greatest when the temperature of the fixed specimen is held constant. The TE 77/WEAR system is ideal for establishing long-term wear rates and transition points.
TE 77/PROFILE In situ Profilometer
Every time a measurement is programmed, the reciprocating specimen head is automatically withdrawn to the stroke end furthest from the profilometer. The start position for a measurement is approximately 1 mm past the mid-stroke position and the end position on the un-worn part of the specimen, beyond the stroke end. The measurement thus covers just over half the wear scar, plus part of the unworn surface, which may subsequently be used as a reference for more detailed analysis.
In situ wear
Note that the wear may be “negative”, indicating adhesive material transfer from the moving specimen to the fixed specimen plate. Adhesive transfer will frequently be accompanied by higher levels of friction, compared with mild abrasive wear. In this example, the fully formulated lubricant prevents adhesive wear.
TE 77/GB/20 Gearbox for 20:1
This gearbox mounts between the drive motor and camshaft, providing a 20:1 reduction in operating frequency. The low sliding speeds generated encourage the contact to operate in boundary lubrication conditions. The option is therefore useful when testing additives and lubricant formulations.
TE 77/GB/100 Gearbox for 100:1 Reduction
This gearbox mounts between the drive motor and camshaft, providing a 100:1 reduction in operating frequency. The very low sliding speeds generated ensure that the contact operates in boundary lubrication conditions. The option is used for studying static friction and stick-slip of lubricants for slide-ways, clutches and the like. Specimens are available for stick-slip testing.
TE 77/HR Heated Piston Ring Sample Carrier
The TE 77/HR is a replacement reciprocating specimen carrier with integral heating, designed to allow tests to be run with a differential temperature between the moving ring specimen and the fixed liner specimen. The ring sample is self-heating to 200°C and is normally used in conjunction with liner sample temperature controlled by the fixed specimen heater block to less than this value.
TE 77/INERT Gas Enclosure
The TE 77/INERT Gas Enclosure is an anodised aluminium chamber that fits in place of the standard heater bath and encloses the fixed and moving specimens. The reciprocating specimen carrier is sealed by a rubber bellows fitted between the reciprocating drive assembly and the chamber. Load is applied through a flexible membrane in the top of the chamber.
Inlet and outlet pipe fittings and a length of pipe are provided for connection to a customer’s inert gas supply. A water manometer is used to measure the gas pressure in the enclosure. Specimen temperatures in the chamber are limited to 200°C.
This option is used for investigating the effects of ambient gas or moisture on friction and wear. Inert gases, water vapour and mildly corrosive gases may be used.
TE 77/800C High Temperature Heater
On the TE 77 the heated specimen carrier and piezo-electric force transducer are mounted on a common sub-base. To carry out high temperature experiments this is replaced with the separate TE 77/800C sub-base assembly. Key components of this assembly are made from Inconel (for high temperature performance) and a thermal barrier ensures that the flexures and piezo-electric force transducer are not exposed to excessive temperature.
The standard reciprocating specimen carrier head is also replaced by a carrier made from Inconel. This has a “C” shape, permitting the specimens to be enclosed inside a shroud and the load to be transmitted through a roller bearing outside this enclosure.
Specimens can be mounted either in the standard sample bath for dry or lubricated tests up to 600°C or on a special platform for high temperature un-lubricated tests. A stainless steel shroud is provided to help reduce heat loss by radiation and convection at the high temperatures.
This option may be provided as a retrofit assembly comprising heater block and four 200 W heaters, flexures and piezo-electric force transducer all mounted on a separate sub-base. The heaters are wired into the same connector as the standard heaters once these have been removed.
TE 77/PUMP Peristaltic Pump and Drip Feed System
The TE 77/PUMP drip feed system uses a variable speed peristaltic pump. The advantages of this system are that there is no cross-contamination between pump and fluid, fluids are not exposed to high shear rates, it is self-priming and safe under dry running. By selecting a range of tube bore diameters a very wide range of flow rates are achievable. With a single size of tube the pump has a 110:1 turn ratio.
The package includes the peristaltic pump controller and pump head, three sizes of pump tubing and universal pipe fittings. An adaptor is provided for use with the standard moving specimen carrier clamps. This allows a PTFE tube to be mounted on the carrier to direct lubricant onto the contact zone.
This option is used in additives screening and lubricant development programs to provide fresh lubricant to the contact over long time periods. This is particularly important if tests are being carried out at temperatures where oxidation or evaporation of the sample is accelerated.
TE 77/PIEZO Fretting Test Adapter
This adapter replaces the standard reciprocating drive assembly with a piezo actuator drive system. This is for performing fretting tests at strokes from 10 to 100 microns with frequencies up to 100 Hz with control of mid-stroke position and amplitude to +/-0.2 microns.The system includes a high pre-load piezostack, servo amplifier and signal generator, capacitance displacement gauge, 250 kHz 16-bit 16 channel multi-function ADC (not required if TE 77/HSD is already installed) and C-flex mounted moving specimen carrier. Simultaneous high speed data acquisition of friction force and displacement allows force-displacement curves to be plotted.
TE 77/PD Pin on Disc Test AdapterThe TE 77/PD Pin on Disc Adapter replaces the standard reciprocating head on the machine and allows the performance of conventional pin on disc tests, using the machines drive motor and automatic loading system.
TE 77 Slide/Roll Adapters
Many wear and failure mechanisms in gears and valve trains can be modelled with sliding-rolling contacts, in which the point of contact moves on both surfaces. The development of the “Energy Pulse” (EP) criterion led to the development of two slide-roll adapters for the TE 77.
TE 77 EP-CAMIn this arrangement, a plate specimen is reciprocated against a rotating roller in what has been termed a “Reciprocating Amsler” test configuration. This produces asymmetrical lubricant entrainment: positive with the surface of the plate and roller moving in the same direction and, depending on relative speeds, negative when moving in opposite directions, hence a model for the kind of entrainment conditions occurring in a cam-follower contact. No point on either specimen remains in continuous contact.The adapter uses the standard 25 mm stroke cam drive and loading system. It is supplied on an sub-base, interchangeable with the standard TE 77 heated specimen carrier and piezo-electric force transducer sub-base. The TE 77/EP-CAM test roller is mounted on the output shaft of a worm gearbox and runs in a heated lubricant reservoir. The reservoir is supported on flexures and a piezo-electric force transducer measures the horizontal (traction) forces in the contact. The enclosure is provided with an integral electric heater and thermocouple to enable tests with bulk fluid temperatures up to 100°C.
The worm gearbox with has a 2:1 speed reduction and the input shaft is connected via a 1:2 ratio bevel gearbox to a servo-motor. The rotational speed of the roller can be adjusted independently of the reciprocating rate of the plate, allowing a range of different varying entrainment velocities to be set. In addition to adjusting the varying slide/roll ratio by adjusting the rotational speed and reciprocating frequency, the stoke length can of course be adjusted.The upper plate specimen is secured to a pivoted yoke on the reciprocating drive. This ensures that the plate aligns with the roller with an even load distribution across the contact width. The load is transferred to the reciprocating arm by the usual method of the needle roller cam follower running against a plate on the lower side of the loading yoke.
TE 77 EP-GEARIn this arrangement, a roller is reciprocated against a plate specimen and a rocking motion induced by a linkage mechanism. The entrainment velocity varies with stroke, symmetrically about the mid-stroke position. The result is that the point of contact moves on both specimens, similar to gear teeth sliding and rolling about the pitch point. No point on either specimen remains in continuous contact.
The adapter replaces the standard machine reciprocating head and thus uses the standard 25 mm stroke cam drive, loading system and fixed specimen assembly. Slide-roll ratio is adjusted by altering the position of the link arms.
TE 77/LLA Dead Weight Low Load Adapter
There are a number of test procedures requiring low levels of normal load. These include tests on coatings and soft layers, the evaluation of the lubricity of fluids and the ISO/DIS 12156-2 Fuel Lubricity Test. The standard automatic loading system has a loading threshold of 5 N. The Low Load Adapter can apply loads down to fractions of a Newton, although the minimum resolvable friction forces are at a level of 2 N normal load.
The Low Load Adapter applies dead weight loading to a ball (point contact) moving test specimen. The adapter uses a balanced beam and a push rod running through a linear bearing in a modified specimen carrier. This ensures that the load remains vertically above the ball across the whole stroke. The design limits the stroke to 2 mm with this adapter.
TE 77/TB ISO Test Bath
This test bath is for use in conjunction with TE 77/LLA for performing tests using standard ISO Fuel Lubricity Test specimens.
TE 77/D5706/7 Fixed Specimen Bath
TE 77/D5706/7 Fixed Specimen Bath, in conjunction with the standard reciprocating head, allows fixed and moving specimens as specified in ASTM D5706 and D5707to be accommodated.
TE 77/CAL Calibration Kit for Load and Friction
The two most important parameters to calibrate on the TE 77 are the normal load and the friction force. TE 77/CAL provides a pivoted beam with dead weights able to apply up to 1,000 N to the loading system and a pulley, cord and weights to apply a tangential force to the specimen bath to check the friction measurement.
