Abstract
Stainless steel Rex-734 biomedical alloy ( ASTM F1586 ) can be used as a new functional implant material with its extra ordinary corrosion resistance and material properties. In order to functionalize such material, Single Hydroxyapatite(HA) (S 1 ), Hydroxyapatite-SiO 2 (S 2 ), Hydroxyapatite-Ag (S 3 ) and Hydroxyapatite/Zr (S 4 ) dip coatings were executed on Rex-734 implant alloy. Different coating thicknesses for S 1 , S 2 , S 3 and S 4 groups were obtained 12.4, 10.9, 11.1 and 10.3 µm, respectively. From the morphologic SEM views, the better and crack free coating surfaces were found for HA/Zr (S 4 ) group. The average hardness values for single HA coatings were found to be 290 HV. In comparison with single coatings, HA/SiO 2 coatings caused lower hardness (261 HV) and higher values (312 HV) for HA/Ag double coatings, however, highest hardness was obtained (353 HV) for HA/Zr coatings.
