Characterization of Hydroxyapatite Coated SS316L for Biomedical Application

Article Preview

Abstract:

This paper focuses on characterization of Hydroxyapatite coated SS316 L using Pulse vapour deposition method. The target material (Hydroxyapatite) has been synthesised chemically in laboratory through the addition of (NH4)2HPO4 with Ca (NO3)24H2O solution. This mixture has been converted in to circular blocks through various processes as explained below and coated over the stainless steel substrate. The morphological characteristics of the coating and surface roughness analysis have done through SEM and AFM. Also the hardness and corrosion resistance of the coating are examined. It has been found that improved hardness when compared with SS316L (175 Hv) to Hydroxyapatite (245 Hv) coated SS316 L. Also the results of corrosion resistance test after 250 Hrs of experiment found that formation of red rust is attained for uncoated samples where as Hydroxyapatite coated samples remains unchanged.
