Nano Tribometer

In Nanotribometry, a flat, a pin or a sphere is loaded onto the test sample with a precisely known force. The friction coefficient is determined during the test by measuring the deflection force on the 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 behaviours of almost every solid material combination with or without lubricant. Furthermore, control of the test parameters such as speed, frequency, contact pressure, time and the environmental parameters (temperature, humidity and lubricant) allows us to closely reproduce the real world conditions of a practical wear situation.

The Nano Tribometer offered by Warsash Scientific is a unique instrument because of its low load range down to 50µN. It can perform both the linear reciprocating and rotating mode. One important feature is that the experiment stops automatically when the coefficient of friction reaches a threshold value or when a specified number of turns are reached. Also, the Tribometer is supplied with an enclosure so that a controlled atmosphere of varying humidity or composition can be used. Specialised versions of the Tribometer have been developed for high and low temperature operations, reciprocating motion and high vacuum testing. It is equipped with a depth measuring sensor for real-time display of depth information which is important in studying the time dependent wear properties. An electrical conductivity option can enable testing of electrical insulation of coatings.
