In Tribology, a flat or a sphere shaped indenter is loaded on to the test sample with a precisely known weight. A pin is mounted on a stiff lever, designed as a friction less force transducer. As the sample is either rotating or sliding, resulting frictional forces acting between the pin and the sample are measured by very small deflections of the lever. Wear coefficients for both the sample and material are calculated from the volume of the material lost during a specific friction run.
This simple method facilitates the determination and study of friction and wear behavior of almost every solid state material combination, with varying time, contact pressure, velocity, temperature, humidity, lubricants, etc. | ||||||||||||||||||||||||

Tribometer
The High Vacuum Tribometer has been designed to provide controlled vacuum conditions (e.g. space) or gaseous environments. The highly efficient vacuum control system allows the user to reach the desired atmospheric condition very fast but in a controlled way.
For reasons of security and energy conservation, the analysis of friction and wear properties of materials at elevated temperatures is becoming increasingly important, especially for the development and quality control of combustion engines and power plants. To meet the resulting demand of instrumentation, CSM Instruments has extended its range of pin-on-disk Tribometers with a powerful high-temperature version which can accurately simulate in-service conditions.
The control of friction and wear in moving machine parts is a critical issue facing the manufacturing industry. It is important to have comparable analysis data obtained over a period of years, at varying humidity and temperature and in the presence of lubricants.
In Nano tribometry, a flat, a pin or a sphere is loaded onto the test sample with a precisely known force. The pin is mounted on a stiff lever, designed as a frictionless force transducer. The friction coefficient is determined during the test by measuring the deflection of the elastic arm.
