Friction tester
Last Updated December 27, 2018
Introduction of friction tester (ball-on disc) equipment
Overview
Principles
Place the specimen on the disc and place the ball on the surface of the specimen. Apply the weight of the ball to rotate the disc. This creates frictional force on the ball and the surface of the specimen, and the sensor measures the friction force. The friction coefficient can be known when removing frictional force by the loaded load.
Characteristics
In addition to measuring the frictional force of the specimen surface, the wear characteristics can be evaluated by surface observations of friction between the sample and the ball using a microscope.
Caution
During the friction test, cutting may be required to place the sample on the specimen table.
Equipment Performance and Specifications
Instrument model number: CSM Tribometer
Date of introduction: September, 2005
Example of measurement
