Abstract
Normal load can affect the wear performance of the materials. with the normal load increased, friction coefficient is firstly increases and then decreases, when the normal load is 80N, the minimum friction coefficient is 0.916; rotating speed can effect the wear performance of the materials with the change of rotating speed, the faster the speed, the bigger the friction coefficient When the speed is 60 rad/min, the minimum friction coefficient is 0.918.The content of VC can influence greatly for wear-resisting performance, when the content of VC was 55%, the wear performance of material is better, the friction coefficient is 0.916-0.918.The results show that: the microstructure analysis can judged that, in the wear process, iron is off first, then the particle phase, so VC grain can intensify the wear resistance.
