摘　　要：阳极氧化表面处理技术在医疗器械产品中广泛应用,氧化膜不同颜色可以区分各个部件,有利于手术的进行。氧化膜表面呈现多孔结构,有利于细胞附着生长,氧化膜的存在能够保护基体避免腐蚀。表面元素分析表明,氧化膜除含有基体元素外,还含有少量Na、P、Si、Ca等元素,不同厂家生产的阳极氧化膜表面元素种类及含量略有差异。Anodic oxidation surthce treatment technology has been widely applied in the medical devices, difl;erent colors can differentiate eacb component, it is in Ihvor of the operation. The film shows porous structure is conducive to cell adhesion and growth, it is also protect the substrate from corrosion. Except the substrate elements, the film also contain a small amount of Na, P, Si,Ca and other elements, the amount and the types of the elements on the anodic oxidation coating are different produced by different manufacturers.
