Investigation of the Effect of Thermal Oxidation Process on Coating Efficiency in Ti6Al4V Samples Coated with Hydroxyapatite (HA) by Electrophoretic Deposition (EPD) Technique

Abstract

In this study, the effect of thermal oxidation treatment on Ti6Al4V alloy in the HA coating by Electrophoretic Deposition (EPD) technique was investigated. For this purpose, the HA powders were produced by chemical precipitation method and characterization studies of produced hydroxyapatite powders were carried out by X-Ray Diffraction (XRD), and powder size analysis. Then, thermal oxidation process was applied to Ti6Al4V samples at different temperatures. The surface roughness of Ti6Al4V samples were measured in order to determine the thermal oxidation effect on Ti6Al4V surface. Then, HA coating was pruduced on Ti6Al4V at the determined voltage and time by EPD process. HA deposition efficiency on Ti6Al4V was determined according to thermal oxidation process. The obtained results showed that the thermal oxidation process affects the coating efficiency positively.
