Tribological analysis of wire additive manufactured Ti6Al4V by Electron Beam source

Abstract

Additive manufacturing through electron beam, is an attractive and fast growing additive manufacturing process for complex geometry in the aerospace, automotive and rapid tooling industry. Ti6Al4V is the material which is widely used in aerospace industry owing to its good strength-to-weight ratio, higher strength and toughness and admirable corrosion resistance. Ti6Al4V samples were realized through wire electron beam additive manufacturing by Pre-positioning the wire and then fusing it to the substrate material. The samples were subjected to standard dry sliding wear test to explore the wear behaviour. The wear analysis exposed the substantial effects of parameters on the wear rate. Likewise, the mechanisms that significantly influenced the wear rate was identified with worn surface and debris analysis.
