Abstract

In this study, in order to fabricate sintered dental implant, the effects of HA, Ti and TiN on corrosion and biocompatibility, cell toxicity, osseointegration of electroless Cu-plated and sintered stainless steel implant were investigated using various characteristics. The effects of Ti/TiN/HA coating on the interface activation and surface characteristics of sintered stainless steels(SSS) by electron-beam physical vapor deposition(EB-PVD) method have been studied. Stainless steel compacts containing 2, 4, and 10 wt%Cu were prepared by electroless Cu-plating method which results in the increased homogenization in alloying powder. The specimens were coated with HA, Ti and TiN with few $\mu\textrm{m}$ thickness respectively by EB-PVD method. The microstructures and phase analysis were conducted by using SEM. Biocompatibility were investigated in experimental dog. The corrosion behaviors were investigated using potentiosat in 0.9% NaCl solution and corrosion surface was observed using SEM and XPS.
