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.
A magnetic film was prepared with FeSO4 solution as principal raw material on titanium alloy by mi-cro-arc oxidation method,specific saturation magnetization of the film was 77.7 A??m2/kg.A formation tech-nology 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 Fe3 O4 and (Fe2 O3 )x??2 H2 O crystals,and sur-face of the film was smooth and dense.Formation mechanism of the magnetic film was briefly deduced.
