Abstract

Abstract: Among the large family of NiTi alloys, the NiTi alloy with equal atomic ratio have shape memory effect and super elasticity, Compared with NiTi alloy, thermoelastic martensitic transformation does not occur in the 60NiTi alloy, and it has no shape memory effect and super elasticity. However it has outstanding potential in hardness, corrosion resistance and elastic properties, showing a good application prospect in the aerospace field. The solid solution treated 60NiTi alloy also has structural stability, super corrosion resistance and excellent wear resistance, and has become a candidate new material for aerospace bearings.

Key words: 60NiTi alloy, wear resistance, corrosion resistance, aerospace bearing
