Post Heat Treatment of Plasma Sprayed Pure and Alumina-Titania Reinforced Hydroxyapatite Coating on SS 304 Steel
ABSTRACT
It has been reported by previous research work that in plasma spray process hydroxyapatite decomposes into some amorphous phases due to rapid cooling of the coated substrate during the coating process, which causes instability of coated implant. Post coating heat treatment has been expected to minimize these phases and also enhance the long term reliability of hydroxyapatite coatings on metal substrates. In this paper post coating heat treatment is carried out at different temperatures suggested by the literature to study its effect on the microstructural and mechanical properties of coating. Coated substrates were characterized by X-ray diffraction (XRD) and SEM/EDAX analysis.
