摘要: 研究了低碳钢在镀铁溶液内经对称交流电处理后在表面形成活化膜的组成及厚度,观察了镀铁层与基体界面的形貌,结果发现,活化膜的厚度随活化电流密度而变化,当电流密度为7Adm ̄(-2)时,在表面形成了一个厚度为20~25nm的洁净活化膜,镀铁层与基体结合牢固。探讨了对称交流电对阴极表面的作用机理。

Abstract: The composition and thickness of active film formed on the surface of cathodemade of low carbon steel after treated by symmetric alternating current(SAC)in ferris chloride bathis studied,and the interfacial morphology of the iron deposit and the substrate is also examined.Theresults show that the active film,which a thickness of 20~25nm can be obtained under SAC densityof about 7A dm ̄(-2) ,so that the adherent iron deposit can be achieved on the active film. The effect ofSAC on cathode surface is discussed in detail.

Key words: Iron plating without anodic etching, Symmetric alternating current, Activation
