Abstract

This paper aims to investigate the microstructure and wear properties of Ti6Al4V induced by shot peening. Shot peening process has been used in order to improve the surface and frictional properties of materials, and also used to develop the compressive residual stress layer and enhance the mechanical properties of Ti6Al4V alloy. A pin on disc tribometer is used to carry out the wear test in Ti6Al4V material before and after shot peening. The effects of surface roughness, microstructure hardening induced by shot peening on the tribological properties of Ti6Al4V alloy are evaluated.

Keywords: shot peening, Ti6Al4V, surface roughness, wear
