| Abstract | ||||
| In this work, the study of thermal treatment by laser, plasma glow discharge, and tubular furnace on Ti-6Al-4V alloy coated with hydroxyapatite (HA) by methods of dip coating and electrophoretic deposition. The effect of pulsed Nd:YAG laser , oxygen plasma and tubular furnace treatments on structure, morphology and corrosion resistance of HA coating –Ti6Al4V alloy samples were thermal reported. The samples were tested by optical microscope, XRD, SEM, and the corrosion characteristic with open circuit potential (OCP) and polarization curve (Tafel). The results showed that the samples thermal reported by tubular furnace were the best where the corrosion rate was reduced to 3.567×10-4 mm/y for the dip-coated samples and 7.221×10-4 mm/y for the electrophoretically deposited samples compared with 9.396×10-3mm/y for uncoated sample. It was found that the heat, laser and plasma treatment enhanced the structure and corrosion resistance properties of the HA coating on Ti6Al4V substrate for use in biomedical applications. This research demonstrates a new low-cost approach to produce high corrosion resistance biocompatible materials. | ||||
