EXPERIMENTAL INVESTIGATION ON SURFACE MORPHOLOGICAL BEHAVIOR OF HYDROXYAPATITE COATINGS DEPOSITED OVER METALLIC BIOMATERIAL SURFACES USINGPLASMA SPRAY PROCESS

摘要

Metallic biomaterials are of great interest due to their higher mechanical properties. Metallic materials have very high tensile strength, fatigue strength, and fracture toughness as compared to ceramics and polymers. Due to these key properties, metallic materials are the widely used biomaterials for replacing the structural parts of the human body. In this research work, coating of hydroxyapatite has been performed over the metallic biomaterial surfaces using Plasma spray process. The coating expected to form a protective layer over the substrates with good adhesion which helps in achieving improved tissue growth of the implant. The coated samples were examined for surface morphological behavior using Scanning Electron microscope (SEM), Energy dispersive spectroscopy (EDAX) and Fourier – transform infrared spectroscopy(FTIR).
