| 摘 要： | 目的 应用微弧氧化和水热处理技术在纯钛表面制备TiO2/HA梯度涂层,并对该涂层成分、形貌等理化性能进行评价.方法 纯钛试件分为三组,分别进行微弧氧化处理(M组)、微弧氧华-水热处理(M H组)和纯钛对照(C组).采用扫描电镜观察表面形貌并用X线衍射对其进行成分分析,通过划痕实验检测膜基结合力.结果 做弧氧化处理后试件表面呈现多孔状,主要为锐钛矿型TiO2;经过后续水热处理,从扫描电镜(SEM)照片可以看到试件表面析出一层白色柱形结晶体,同时X射线衍时仪(XRD)潜线出现了羟基磷灰石的衍射峰.结论 微弧氧化及水热处理能够增强纯钛种植体的生物相容性.

| Abstract: | Objective To prepare the bioceramic gradient film by microarc oxidation(MAO)-hydrothermal treatment and evaluate its composition and microstructure.Methods Sixty samples of pure titanium were prepared and divided into three groups of MAO treatment(group M),MAO and hydrothermal treatment(group M-H) and pure titanium control(group C).XRD and SEM were employed to characterize the phase,composition and microstructure of the films.The bonding force of film was detected by scratch test.Results The pores were well... |
