Laser cladding of Inconel 625-based composite coatings

Abstract

Inconel 625-based composite coatings reinforced by WC and Cr3C2 particles have been produced via a diode laser cladding process. The effect of heat input level and morphology of the reinforcing particles on the degree of their dissolution has been established. Additionally, the influence of the morphology of the reinforcing particles on the erosive wear behaviour of the coatings was studied.
