Thrust Washer Friction Testing Machine ASTM D3702, Tribometer dry friction and wear test

Friction and Wear Testing Machine can be used to evaluate the friction and wear performance of lubricants and materials such as metals, plastics, coatings, rubber, and ceramics under very low speed or high speed with method of Self-Lubricated Rubbing Contact Using a Thrust Washer. 

ASTM D3702: Standard Test Method for Wear Rate and Coefficient of Friction of Materials in Self-Lubricated Rubbing Contact Using a Thrust Washer Testing Machine.

Purpose and Features of the Thrust Washer Friction Testing Machine:

• A. It should be capable of evaluating the friction and wear performance as well as abrasive wear performance of samples such as end faces and pin discs under both ambient and high-temperature conditions in the form of sliding friction.

• B. It can assess the friction and wear performance of various new materials such as metals, engineering plastics, ceramics, and powder metallurgy, measuring the wear resistance of materials and material matching characteristics. Tests can be conducted under various parameters including varying loads, speeds, friction pairs, and environmental temperatures. Samples can be in the form of end faces or pin discs.

• C. The application of test force is controlled by a hydraulic closed-loop servo system, and the magnitude of the test force is set by the operator on the computer interface.

• D. Parameters such as spindle speed, number of rotations, test force, friction torque, temperature of the friction pair, and test duration are all controlled by the computer, which can collect test data in real-time and plot corresponding test curves. Test data or curves can be saved, retrieved, and printed at will.

• E. Equipped with 10 types of friction pairs in a total of 7 sets for lined surfaces and flat surfaces, maximizing testing options for the user.
