Effects of Duration on Wear Rate of a PTFE Composite

Abstract:

A type of PTFE/MoS₂/glass fiber composite has been used as bearing cage material. To study the friction properties, the tests have been performed under various parameters on block-on-ring. The experimental results were as follows: Wear rate of the polymer composites was dramatically affected by test duration. With increase of test duration, the wear rate rapidly decreased. At the sliding velocity of 1.83m/s and load of 45N, the highest wear rate was 8.85×10^-15m³/N·m in the test of duration 0.5h, while the lowest was 0.88×10^-15m³/N·m in the test of duration 10h (the minimum and maximum times examined).
