Abstract
Mo-Si-B alloy is a promising candidate for high temperature environment, while its high temperature dry sliding wear behavior is not yet well investigated. In the present work, the Mo-12Si-8.5B alloy and its composite reinforced with 10 wt% MoAlB ceramic were prepared by spark plasma sintering. Effects of MoAlB ceramic addition on the microstructure, mechanical properties and dry wear properties at RT–1000 °C were investigated. The result indicates that the composite shows an enhanced strength and hardness, and a remarkably improved wear resistance. The excellent wear resistance is mainly attributed to the improved hardness and thermal softening resistance, as well as the formation of Al2(MoO4)3 layer at 800–1000 °C that results from the dispersive distribution of MoAlB particles.
