摘要
采用微弧氧化技术,在钛基体表面生长出一层致密的、结合良好的金属磷酸盐生物陶瓷膜,考察了微弧氧化时间与电流对生成陶瓷膜的影响。并借助XRD、SEM等测试手段,研究了该生物陶瓷膜的物相组成和表面形貌特征。研究结果表明该金属磷酸盐生物陶瓷膜主要物相是CaTi4(PO4)6(CTP)。本技术与粉末等离子喷涂技术相比,具有流程短、能耗小、易于实现的优点。
Bioceramic film was synthesized on the titanium using micro-arc oxidation technique, the influences of treating time and current density of micro-arc oxidation on the synthesis of film was studied. XRD, SEM were utilized to characterize the bioceramic film's compositions and morphology. The results show that the film mainly consisted of CaTi_4(PO_4)_6(CTP). Compared with the CTP powder plasma spray technique, the micro-arc oxidation technique has some advantages, such as short flowsheet, low energy consumption and easy to practice.
