Enhancement of Surface Hardness and Wear Resistance of Inconel 718 by Laser Material Deposition of Titanium and Inconel 718 Powders’ Mixture

In spite of having numerous applications in aerospace, automobile, and marine industries, Inconel 718 suffers from low surface hardness and wear resistance. In the present study, a novel method based on laser additive deposition has been proposed to address this drawback. Crack-free clad layer with much increased hardness up to four times of the IN718 base material could be achieved with 50
