摘 要
采用微弧氧化覆膜工艺方法在TC4合金表面制备了羟基磷灰石(HA)生物涂层，利用XRD对涂层主要生物成分HA进行分析; 并配制模拟人体体液(SBF)，对涂层进行了浸泡试验和耐蚀试验; 利用摩擦磨损试验机对试样进行耐磨损试验。结果表明，制备出HA生物陶瓷涂层在长时间浸泡后，经过降解和沉淀，质量先减少后增加; 磨损量随磨损时间变化，最终呈平稳趋势; 此外试验材料所在SBF的pH由7.1变化到7.8，变化不大，涂层化学稳定性好，耐SBF腐蚀性好。试验结论: 该种涂层材料能够适于生物体体液环境，并具有良好的耐磨耐腐蚀性能。

Abstract
In order to study the wear resistant and corrosion resistant performance of biological coating on titanium alloy, micro-arc oxidation film coating process was used to prepare hydroxyapatite (HA) coating on in TC4 alloy surface, XRD was used to analyze the main biological ingredients of HA coating. And the simulated body fluid (SBF) was prepared, immersion test and corrosion test for the coating were performed. A friction and wear testing machine was used for wear resistance test. The results showed that the HA biological ceramic coating, suffered degradation and precipitation after long soaking time, the mass first decreased and than increased. Wear changed with wear time, and eventually showed a steady trend; SBF solution pH changed from 7.1 to 7.8, only a little change, the chemical stability corrosion resistance of the coation are good. It is concluded that this kind of coating material can be suitable for biological fluid environment, and has good wear-resisting corrosion resistance.
