Abstract
In suit TiB2 patticles were synthetized by mixing salt reactive process to prepare ZL203 composite. The dry friction and wear behavior of the composites under different loading conditions was investigated. The results show that the TiB2 particles in composite distributed uniformly, their average size was about 500 nm. Compared with matrix material, the mechanical properties and wear resistance of the composites increased obviously, and the occurrence of serious wear under the condition of large load was prolonged. A compact mechanical mixture layer was deformed on the friction surface of the composite, and it had good protection to composite.
