Effects of Boriding on Cavitation Erosion Resistance of Ti6Al4V Alloy

Abstract:

A pack boriding technique was employed to obtain a hard coating on the surface of Ti6Al4V alloy in this paper. The microstructure, surface appearance, hardness depth profile and the cavitation erosion behavior of the borided samples in 3.5% NaCl solution were examined. The cavitation erosion resistance of the borided samples was significantly improved as compared with the untreated samples. Increasing in the surface hardness and the compact boride layer contribute to the significantly enhanced cavitation erosion performance of Ti6Al4V alloy.
