摘要/Abstract

摘要： 利用金相显微镜观察了Ni-Cu-P化学镀层的表面形貌,采用浸泡法与电化学阻抗谱测试了Ni-Cu-P 镀层在不同浓度氢氟酸溶液中的耐蚀性。结果表明,Ni-Cu-P镀层均匀、致密,在氢氟酸介质中表现出良好的耐蚀性能,且随着氢氟酸溶液浓度的增大,镀层的腐蚀速率呈先升高后降低的趋势。

Abstract: To study the corrosion of Ni-Cu-P electroless coating in different concentrations HF solution,surface morphology of Ni-Cu-Pcoating was analyzed by metalloscope graphic.The corrosion resistance of Ni-Cu-Pcoating was tested by soaking method and electrochemical impedance spectroscopy testing in different concentrations HF solution.The results show that Ni-Cu-P coating is uniform,dense and has good corrosion resistance in HF solution.With the increase of HF concentration,the corrosion rate ofthe coating appears to increases then decreases in different concentrations of HF solution.

Key words: Ni-Cu-Pcoating , Corrosion resistance , Hydrofluori cacid , Electroless plating
