利用线性极化法、极化曲线法和交流阻抗技术研究了化学镀非晶态Ni-P和电镀纳米Ni处理的碳钢在高温无氧水中的腐蚀电化学行为.结果表明,功能镀镍薄膜/碳钢复合材料在高温无氧水中的腐蚀是在电偶腐蚀条件下因氢去极化引起的电化学腐蚀,腐蚀的特征是点蚀,腐蚀的程度取决于镀层的均匀程度和镀层自身的耐蚀能力.
The electrochemical corrosion behaviour of electroless amorphous Ni P coating/carbon steel substrate and electro deposited nanocrystalline Ni coating/carbon steel substrate were studied by linear polarization, potentiostatic curve and AC impe
