Biocompatibility. Titanium is considered the most biocompatible metal due to its resistance to corrosion from bodily fluids, bio-inertness, capacity for osseointegration, and high fatigue limit. Titanium's ability to withstand the harsh bodily environment is a result of the protective oxide film that forms naturally in the presence of oxygen.
Some ceramic materials commonly used in joint replacement are alumina (Al 2 O 3), zirconia (ZrO 2), silica (SiO 2), hydroxyapatite (Ca 10 (PO 4) 6 (OH) 2), titanium nitride (TiN), silicon nitride (Si 3 N 4). A combination of titanium and titanium carbide is a very hard ceramic material often used in components of arthroplasties due to the ...
