摘要
向传统化学镀金液中添加一种含羟基和有机膦混合缓蚀剂A,研究了其对镍层的缓蚀作用、镀速、镀金层耐蚀性和镀金层附着力的影响。结果表明:镀金液中添加该缓蚀剂后,对沉积过程的镀速无较大影响。所得镀件镍层腐蚀深度从1.85μm降到接近0μm,缓蚀率接近100%。镀金液中随着缓蚀剂A添加量的增加,镀金层附着力明显提升,拉脱强度最大可提高73.37%。此外,添加缓蚀剂后所得镀金层耐蚀性也显著提升,所得镀金层表面无明显孔洞、裂纹,镀层致密且平整。
A new type of corrosion inhibitor A was added to the traditional electroless gold plating solution,and its effect on the corrosion inhibition of the nickel layer,the plating speed,the corrosion resistance of the gold plating and the adhesion of the gold plating were studied.The results show that after adding the corrosion inhibitor,the plating speed is hardly affected.The corrosion thickness of the nickel layer of the obtained plating parts is greatly reduced from 1.85μm,and the corrosion inhibition rate is close to 100%.And with the addition of corrosion inhibitor A,the adhesion of the coating is greatly improved,and the pull-off strength can be increased by 73.37%at the maximum.In addition,the corrosion resistance of the gold plating layer obtained after the corrosion inhibitor is added is also significantly improved,and the surface of the gold plating layer obtained is dense and smooth,without obvious holes or cracks.
