Tribometer

Overview

In tribometry, a sphere, a pin or flat 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. Wear coefficients for the pin and disk materials are calculated from the volume of material lost during the test. This simple method facilitates the study of friction and wear behaviour of almost every solid state material combination with or without lubricant. Furthermore, the control of the test parameters such as speed, frequency, contact pressure, time and environmental parameters (temperature, humidity and lubricant) allows simulation of the real life conditions of a practical wear situation. Tribometers are unique instruments designed for ultra high precision force measurement. They can conduct both linear reciprocating and rotating modes. One important feature of all CSM Tribometers s that the experiment stops automatically when the coefficient of friction reaches a predefined threshold value or when a specified number of cycles is reached. Also, the tribometer is supplied with an enclosure so that controlled atmospheres of varying humidity or composition can be used. Specialized versions of the Tribometer have been developed for high & low temperature operations, reciprocating motion and high vacuum testing. The CSM Tribometers can be equipped with a depth measuring sensor for real-time display of depth information which is important in studying the time dependent wear properties. Furthermore, an electrical conductivity option allows testing of electrical insulation of coatings.
