Pure and 10 wt% 80Al₂O₃-20TiO₂ reinforced hydroxyapatite coatings were successfully deposited on Ti6Al4V substrate by plasma spray technique for bio medical applications. Post coating heat treatment was carried out to study the effect of heat treatment on improvement in micro structure and mechanical properties of coatings. Coating was characterized by SEM/EDAX and XRD analysis. Positive impact of post coating heat treatment was observed in microstructure, surface roughness and micro hardness of both coatings.
