    Characterization of a Duplex Coating (Boriding plus Hydroxyapatite) on Austenitic Steel
    Bahçepinar, AI; Ayvaz, SI; Aydina, I
    In this study, duplex coating process (Boriding + Hydroxyapatite) was applied to 316L stainless steel alloys. Before coating, the substrate materials were shotblasted with 300-500 mu m glass beads in a vacuum type shot blast machine. Tribological properties of the alloy with boriding process, its bioactivity and biocompatibility was increased with the hydroxyapatite (HA) coating process. Powder pack boriding technique was used in boriding process and Electrophoretic deposition method (EPD) was used in HA coating process. At the end of the study, the microstructures (SEM), elemental analyzes of the coating surfaces (EDS), Ca/P ratios, coating thicknesses were determined. In addition, the hardness and adhesion qualities of the boride layer were determined. When the results obtained are evaluated, duplex layers were successfully formed for all parameters.
