低压沉积-微弧氧化制备钛金属HA-TiO2复合膜层
HA/TiO2 Composite Coatings Prepared by Low Voltage Deposition and Micro-arc Oxidation
摘要
Abstract
hydroxyapatite (HA)/TiO2 composite coatings with bioactive on the titanium alloy surface was prepared by low voltage deposition and micro-arc oxidation. The phase structure and surface morphology of coatings were analyzed by XRD and SEM respectively. The effects of deposition parameters on the HA content in film and surface morphology were discussed. The results show that low voltage deposition is necessary condition to synthesize HA/TiO2 composite coatings on titanium alloy. These coatings consist of anatase TiO2, rutile TiO2 and HA. HA is wrapped up in the coating as white cluster, or adheres to surface of these coatings. The HA content in coatings increases with the HA content increasing in electrolytic solution. With HA content increasing, more pores are observed in coating. The HA content in coatings increases with the deposition voltage boosting from 30 V to 120 V. The increase rate of HA content is not obvious when deposition time over 15 minutes.关键词
