摘要：

The biocompatibility of Co-Cr alloy was significantly improved by forming a rough TiO2 layer on its surface. The TiO2 layer was formed by coating the Co-Cr alloy with titanium (Ti) through electron beam deposition followed by microarc oxidation (MAO). When Ti was coated on the surface, the biocompatibility of the Co-Cr 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 ill vitro alkaline phosphatase activity tests. (C) 2008 Wiley Periodicals, Inc.
