Enhanced biocompatibility of CoCr implant material by Ti coating and micro‐arc oxidation
Copyright policy )Enhanced biocompatibility of CoCr implant material by Ti coating and micro‐arc oxidation
AbstractThe biocompatibility of CoCr alloy was significantly improved by forming a rough TiO2 layer on its surface. The TiO2 layer was formed by coating the CoCr alloy with titanium (Ti) through electron beam deposition followed by microarc oxidation (MAO). When Ti was coated on the surface, the biocompatibility of the CoCr alloy was enhanced and it was further improved by the MAO treatment. There were close relationships between the phase, morphology, and thickness of the TiO2 layer and the applied voltage. The biocompatibility of the specimens coated with Ti and subjected to MAO treatment was evaluated by in vitro alkaline phosphatase activity tests. © 2008 Wiley Periodicals, Inc.
