Laser deposition processes for repairing components representing Ti-6Al-4V alloy, 8620 steel having a carburized surface, and Inconel 718 having chromium electroplated surface were evaluated. The objective was to establish processing parameters and deposition materials that could emulate the characteristics of the various surfaces for use as a repair process. Actual parts representing engine drive train components were utilized for these evaluations, and the areas for repair primarily represented bearing surfaces. Evaluations were conducted with deposition materials representing Inconel 718, martensitic SS 431, and martensitic SS 431 with TiC to form a metal matrix composite system. All deposition materials were used in powder form, and the evaluations included detailed characterization of the deposits produced from these materials on Ti-6Al-4V, 8620 steel, and Inconel 718
