Friction and Wear Performance of Ti-Al Matrix Composites under 650°C

Article Preview

Abstract:

Ti-Al alloy matrix self-lubricating composites were fabricated by the method of high temperature hot pressing sintering. The friction and wear performance of self-lubricating Ti-Al matrix composites were studied at high temperature. The study found that the friction coefficient decreased with the increase of solid lubricant, CaF2 and BaF2 had played good lubrication. when the lubricant BaF2-CaF2 mass fraction was 10%, the wear rate of composites to the lowest, it was 0.29×10−7 cm3N-1m-1 in 650°C high temperature.
