Abstract

In the present research, the emphasis has been laid to study the outcome of heat treatment on phases of hydroxyapatite in coatings developed by plasma spraying process. The surface morphology of as-deposited and heat treated HAp coated samples was studied using Scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), and Fourier transformation infrared spectroscopy (FTIR) techniques. The results obtained by XRD analysis of the HAp coated samples after heat treatment reveal the formation of crystalline structure at 700oC with some traces of CaO. Moreover, when the heat treatment was further done at 900oC, the unwanted CaO was totally eliminated and coating with crystalline structure was obtained. Heat treatment reduces the surface roughness and porosity of the HAp coated samples.
