摘要：

以钛金属作衬底,FeSO4溶液为主要原料,采用微弧氧化法制备了磁性薄膜,薄膜的饱和磁化强度为77．7 A?m2/kg.探索了薄膜的形成工艺.运用IR、XRD、XPS和SEM等手段表征了磁性薄膜的组成和形貌,结果表明磁性薄膜主要由 Fe3 O4和(Fe2 O3)x?2 H2 O 晶体组成,表面比较光滑致密.简要推断了磁性薄膜的形成机理.

摘要(英文)：

A magnetic film was prepared with FeSO4solution as principal raw material on titanium alloy by micro-arc oxidation method, specific saturation magnetization of the film was 77.7 A·m2/kg. A formation technology of the film was explored. The magnetic film was characterized by XRD, FT-IR, XPS and SEM etc, the results show that the magnetic film was primarily composed of Fe3O4and (Fe2O3)x·2H2O crystals, and surface of the film was smooth and dense. Formation mechanism of the magnetic film was briefly deduced. ©, 2014, Journal of Functional Materials. All right reserved.
