| 摘 要： | 化学镀中引入稀土元素能显著改善镀层性能。在采煤液压支架立柱化学镀Ni-Cu-P防护的基础上,向镀液中添加不同含量的硫酸铈,研究其对化学镀层形貌、镀速及耐蚀性的影响。结果表明:随着镀液中硫酸铈含量的增加,镀层表面变得平整致密,在硫酸铈的质量浓度为32 mg/L时效果最佳,随后表面又变得粗糙;沉积速率呈现出先增大后减小的趋势,在硫酸铈的质量浓度为24 mg/L时达到最大值27.295μm/h。硫酸铈的加入总体上提高了原化学镀Ni-Cu-P镀层在酸碱盐中的耐蚀性,在其质量浓度为32 mg/L时表现出最好的耐蚀性能。

| Abstract: | The addition of rare earth element could improve the electroless coating properties.Based on electroless Ni-Cu-P coating applied to hydraulic support column,the different Ce(SO4)2 content was introduced to the bath,and the influence of Ce(SO4)2 on the surface morphology,depositing rate and corrosion resistance of Ni-Cu-P coating was studied.The results reveal that,with the increasing of Ce(SO4)2 content,the coating surface becomes smooth and dense,and the best surface morphology is obtained at 32 mg/L of Ce... |
