Laser coating of titanium carbide on stainless steel substrate

Abstract

Laser coating is an advanced material processing technology that has potential to deposit various materials locally on highly non-planar and complex surfaces. It can be used to refurbish or improve corrosion, wear and other surface related properties of the components (base metal). Surface hardness, wear resistance and corrosion resistance are the main properties, we consider in this study. In present study, a pulsed Nd:Yag laser will be used to deposit TiC on the base metal (stainless steel). Thus produced laser coating samples will be subjected to various mechanical (hardness, wear resistance) and metallurgical (microstructure and composition by SEM and XRD) analyses by changing different laser coating parameters such as laser power, laser scan speeds etc.
