Abstract
Abstract
Titanium and its alloys are extensively used for medical implant material due to their superior biocompatibility, corrosion resistance, and strength. However, fabrication of corrosion free titanium and its alloys is still a challenging task since it might affect the surrounding tissues. Therefore, some protection is needed to enhance the performance of the implants in the body in terms of biocompatibility and corrosion resistance. In this work, the hybrid of gelatin-based forsterite–hydroxyapatite synthesized by the sol–gel process was coated by dip-coating on titanium alloy (Ti6Al4V). The variable concentration effects of forsterite–hydroxyapatite in gelatin matrix and the coating applications on the surface morphology as well as corrosion performance of coated substrates were evaluated. The electrochemical corrosion behaviour was investigated through Tafel polarization curves. Outcomes show that the substrate prepared with 5 wt.% of forsterite–hydroxyapatite has a maximum corrosion resistance, crack-free coating, is hermetic and adherent to the substrate.
