摘要: 目的研究钛片表面经打磨、喷砂处理后对微弧氧化的影响及其微弧氧化后形态的变化与元素构成.方法将直径为15 mm,厚度1 mm的纯钛钛片根据表面处理方法不同分为四组:机械打磨组(grooved,G)、喷砂组(sandblasted,SB)、打磨微弧氧化组(grooved microarc oxidation,GMAO)和喷砂微弧氧化组(sandblastedmicroarc oxidation,SBMAO).采用扫描电镜、X射线衍射仪、能谱分析检测钛片表面理化性质.结果(1)钛片在机械打磨和喷砂的基础上,微弧氧化后表面均呈现出火山口状层叠的孔洞;(2)喷砂微弧氧化组较打磨微弧氧化组有更多细小裂纹;(3)微弧氧化能在钛表面形成一层富含钙、磷元素的羟基磷灰石膜结构.结论(1)微弧氧化对打磨和喷砂钛片表面形态有明显的影响;(2)经微弧氧化后钛片表面呈现出的火山口状层叠孔洞,物理学性能上更易于细胞的爬附;(3)微弧氧化在钛表面所形成的一层富含钙、磷元素的羟基磷灰石膜结构,其钙磷比与牙骨质羟基磷灰石中的钙磷比基本相同.Abstract: Objective To analyze the effect of microarc oxidation on the surface of polished and sandblasted titanium and its physical and chemical properties.Methods The pure titanium with 15 mm of diameter and 1mm of thickness were divided into 4 groups:G surfaces,SB surfaces,GMAO surfaces and SBMAO surfaces.Scanning electron microscopy(SEM),X-ray diffraction(XRD)and energy spectrum were used to test the physical and chemical properties of titanium surface.Results(1)On the basis of grinding and sandblasting,MAO surfa...
