Tribometer: measurement of friction and wear of materials
Optimizing tribological performance using the tribometer
The tribometer is an essential measuring instrument for assessing the tribological properties of materials, including friction, wear, and lubrication. It is widely used in industrial sectors where the durability and strength of contacting components are critical. Its advanced simulation capabilities help optimize material performance and improve longevity.
How does a tribometer work?
The tribometer works by simulating the interactions between two surfaces in relative motion, under a controlled load. Depending on the needs, it can:
- Apply specific forces to replicate real-life usage conditions.
- Perform various movements: rotation, linear translation, oscillation, impact.
- Measure critical parameters such as friction coefficient, mass loss and wear depth in real time.
The data collected makes it possible to compare the performance of different materials and adjust formulations or treatments to improve their effectiveness.
Technical characteristics of the tribometer
tribometers and specific experimental conditions:
- Variable load ranges : from a few millinewtons (mN) to several kilonewtons (kN), depending on the tests required.
- Adjustable sliding speeds : from a few micrometers per second to several meters per second.
- Tests in controlled environments : temperatures from -120°C to +1000°C, under vacuum, in an inert atmosphere, in a humid or corrosive environment.
- Compatibility with various industry standards : ASTM G99 (rotational friction wear), ASTM G133 (linear friction), DIN 50324 (friction measurement).
- Advanced sensors : high-precision data acquisition to measure friction force, wear rate and temperature variations.
