【摘要】 测定了不同含铁量的电镀 Ni-Fe 合金的稳态腐蚀电位.用恒电流阳极溶解法测定了不同组合体系的层间电位差曲线,并用“EC”法检测了这些组合体系的耐蚀性。确证三层 Ni-Fe 体系比双层 Ni-Fe 体系的耐蚀性好.三层 Ni-Fe 体系中以半光亮 Ni-10Fe/光亮 Ni-45Fe/光亮 Ni-10Fe/Cr 体系的耐蚀性最优,且超过作为对比的 Cu/半光亮 Ni/光亮 Ni/Cr 体系。更多还原

【Abstract】 The steady state corrosion potential of the electroplated nickel-iron alloys with different iron contents has been measuted.The potential diffe- nce curves of any two adjacent layers have also been measured by the galv- anostatic method for anodic dissolution.The corrosion resistance of various multilayer plating systems’ has been examined by the EC(Electrolytic Corrosion) test as developed by Saur and Basso. Experimental results show that the corrosion resistance of the multilayer plating system of semibright Ni-10Fe/bright Ni-45Fe/bright Ni-10Fe/ Cr is better than that of Cu/semibright Ni/bright Ni/Cr.更多还原
