Abstract

Laser surface hardening is one of the effective methods to enhance the mechanical properties of localised surface area of engineering parts made of different types of steels and other metals like ultra-high strength steel etc. Laser surface hardening has many advantages over conventional hardening process like, self-quenching, very fast, control over energy input and localised hardening etc. In order to further improve the surface quality and mechanical properties of 30CrMnSiNi2A ultra-high strength steel parts fabricated by laser deposition manufacturing (LDM). The quenching modified layer was prepared on the surface of 30CrMnSiNi2A steel by laser quenching technology. This work presents the effect of different laser parameters on the surface morphology and mechanical properties of 30CrMnSiNi2A steel after laser hardening. The experimental data of OM morphology, microstructure, micro-hardness and wear property of hardened layer were analyzed by using the methods of range analysis. Effects of these parameters over the micro hardness of the surface are described. It has been found that, there is around 20% increase in hardness after laser hardening. It considerably debased the surface roughness and wear rate of LDM 30CrMnSi2A alloy parts, which has decreased by 53% and 57% than without laser surface hardening parts. Accordingly, industrial applications of laser deposition manufacturing 30CrMnSi2A alloy parts were supposed to be widened by this study.
