In the present investigation, cobalt based coating powder namely Stellite-6 was sprayed on titanium alloy (Ti-31) when used in gas turbines by high velocity oxy-fuel method. The microstructure and mechanical properties of the coatings were characterized like coating thickness, density, porosity, surface roughness and micro hardness. The advanced characterization of using advanced microscopy of X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM/ EDX). Followed by fracture toughness of the coating was measured by Palmqvist method. The very good bonding strength between coating and substrate material were identified.
