Abstract
Titanium was the most commonly used metal in orthopedic implant. However, no direct chemical bond would be possible between the implant and surrounding bone tissue, and so the titanium implants lack the potential to induce rapid bone formation. Coating the titanium with a bioresorbable and osteoconductive layer would have a significant osseointegration. The purpose of this study was to fabricate and characterize calcium carbonate coating. The coating was fabricated on Ti substrate by converting of CaO coating in humidity environment under CO2 flow. The CaO coating was deposited by sandblasting process. The CaCO3 coating was approx. 1.85 µm thick and covered the surface’s surface uniformly. The coating strength was approx. 16.1 MPa and the Ca content in the coating was 2.02 mg/mm2.
