<p>TiC-Co composite coating has been developed on Ti64 alloy by powder preplacement type tungsten inert gas (TIG) cladding technique, and the consequence of heat input on its microstructure, phase composition, microhardness, and wear behavior was analyzed. The experimental results indicate almost gradual increment of the clad track width and the thickness for increasing heat input during the TIG arc scanning. Although adequate coating thickness was achieved for all different heat input conditions, an inhomogeneity in the coating morphology was witnessed because of discrepancies in the densities, thermal conductivities, and melting points between TiC and Co, and solidification mechanism of the coating constituents. The hardness of the TiC-Co composite coatings enhanced drastically as compared to the Ti64 alloy substrate. Accordingly, the wear resistance of the coating was improved than the substrate, when tested separately against H13 steel and alumina abrasive disk. Nevertheless, slight decline in the hardness and wear resistance properties was noted for increasing the heat input, which primarily occurred due to prominent melting of the TiC particles, and their dilution within the matrix phase. </p>
