Tribological test under extreme conditions
Hundreds of key components that are used in the aerospace industry need full scopes of material testings. AMT offers testers to measure fretting resistance, friction, fatigue, coating adhesion, wear resistance, hardness and many more.
TE 68 Gas Jet Erosion Rig
TE68 Gas Jet Erosion Rig is an important wear mechanism in industrial applications. It fulfills the ASTM G 76 standard. The TE 68 Gas Jet Erosion Rig uses a larger nozzle of 4.7 mm bore and 300 mm long. This means that operating pressures are very much lower.
Technical Specifications
- Velocity: 25 to 80 m/s at 1.5 bar pressure or 120 m/s at 4 bar pressure
- Feed Rate: 0.2 to 2 g/minute
- air heating: up to 100 °C

TE 76 Two Station Reciprocating Vacuum Tribometer
The TE 76 Vacuum reciprocating tribometer is a two-station, vertical axis, long stroke reciprocating tribometer, which combines the reciprocating drive mechanism and fixed specimen mounting from the TE 77 High Frequency Friction Machine with a UHV test chamber.
Technical Specifications
- Load Range: 1-100N
- Laboratory Chiller: -35°C to 150°C
- Frequency Range: 2-25Hz
- Pressure: Atmospheric to 100 Picobar (10-5 Pa)

TE 91 Precision Rotary Vacuum Tribometer
The TE 91 PrecisionVacuum Rotary Tribometer is based on a bench mounted test chamber. A motor driven test spindle, in the form of standard rotary feedthrough, projects downwards into the chamber and carries tooling for mounting rotating test samples. A servo motor with encoder feedback provides a variable speed turn-down ratio of 100:1. The force applied by the actuator is adjusted by means of a precision servo pneumatic valve. A second force transducer may be mounted inside the test chamber to measure the resulting in-chamber load force in order to calibrate the external load force transducer for different chamber operating pressures.
Technical Specifications
- Load Range: 20-2000N
- Speed:10-1700rpm
- Laboratory Chiller: rt to 80°C
- Pressure: Atmospheric to 100 Picobar (10-5 Pa)

DN 55 High Temperature Dry Sliding & Fretting Machine
The DN 55 High Temperature Dry Sliding & Fretting Machine comprises a special short stroke, minimum trapped oil volume, servo hydraulic actuator, mounted vertically on a massive cast iron base. The actuator incorporates hydrostatic bearings, which, in combination with the minimized oil volume, allows high frequency and short stroke operation. The test assembly is located vertically above the actuator and comprises two fixed specimen arms supported on flexural pivot bearings, which are in turn mounted on linear flexure assemblies. Motion in a vertical direction is restrained by piezo force transducers.
Technical Specifications
- Type of Movement: Sine, Square and Triangular
- Load: 5-2000N
- Stroke – continuously variable: 10 microns to 20 mm
- Resolution:+/- 0.2 microns
- Frequency – continuously variable: 0.1-200Hz
- Maximum stroke at 100 Hz: 30 microns
- Temperature: up to 1200°C
- Dynamic Load: 5.7KN
- Static Load: 8.6KN
