摘　　要：从三价铬溶液中脉冲电沉积制得Fe-Cr合金镀层，并对Fe-Cr合金镀层的表面形貌、成分、结构、耐蚀性等进行了分析。结果表明：Fe-Cr合金镀层表面光亮，无孔蚀，其中Cr元素的质量分数为28．62％，晶粒尺寸分布在2-50nm之间；与304不锈钢相比，Fe-Cr合金镀层在5％的H2SO4溶液中的耐蚀性更好。Fe-Cr alloy coating was prepared by pulse electrodeposition from trivalent chromium electroplating solution. The surface morphology, composition, structure and corrosion resistance of Fe-Cr alloy coating were analyzed. Results showed that Fe-Cr alloy coating with bright surface and without corrosion pits, the mass fraction of Cr element was 28.62%, and the grain size was in the range of 2-50 nm. Compared with 304 stainless steel, Fe-Cr alloy coating exhibits better corrosion resistance in 5 % H2SO4 solution.
