Abstract: NiTi-based alloys with higher Ni content have become an important bearing alloy because of their high hardness, low elastic modulus, good corrosion resistance and nonmagnetic, etc. In present work, recent progress of NiTi-based bearing alloys is comprehensively overviewed, mainly including microstructure, mechanical properties, frictional wear properties and corrosion resistance. The emphasis is laid on the effect of heat treatment and alloying element on mechanical properties of alloys. Some important issues on NiTi-based bearing alloys are discussed.

Key words: NiTi-based alloys, microstructure, hardness, friction and wear
