摘　　要：采用电沉积的方法制备了Ni-Fe合金镀层,对其微观形貌和结构进行了表征,并采用电化学方法研究了所制备的Ni-Fe合金镀层在不同介质中的腐蚀行为。结果表明:在5%硫酸溶液以及3.5%氯化钠溶液中,w(Fe)为19.23%的Ni-Fe合金镀层耐蚀性最好,在5%氢氧化钠溶液中w(Fe)为28.16%的Ni-Fe合金镀层的耐蚀性最佳。Ni-Fe alloy coatings were fabricated by electrodeposition process.The surface morphology and structure of the Ni-Fe alloy coatings were determined,and corrosion behavior of the coatings in various medium solutions were investigated by electrochemical polarization method.The results indicated that Ni-Fe alloy coating which contains 19.23% Fe has the optimal corrosion resistance in 5% H2SO4 and 3.5% NaCl solutions.But in 5% NaOH solution,Ni-Fe alloy coating containing 28.16 % Fe has the highest corrosion resistance.
