摘　　要：三价铬盐的二甲基酰胺 (DMF)水溶液体系电沉积 Fe- Cr合金 ,可获得含 Cr12 %～ 6 5 % (质量分数 )的光亮合金镀层。研究了阴极电流密度、镀液 p H值、三价铬盐浓度对镀层成分的影响及合金镀层耐腐蚀性能。Electrodeposition iron/chromium alloys from the DMF plating bath of trivalent chromium salte was studied in this paper.The bright metallic appearance plating coating with a compositional range from 12%Cr to 65% Cr could be obtained.The effects of current density,pH value of the plating bath and the concentration of trivalent chromium salte on composition of the iron/chromium coating obtained and the corrosion properties of these deposits were discussed.
