摘　　要：针对某次主机厂铝合金机盖铆钉镀层附着力不良问题进行了研究,通过显微镜观测、对比分析等试验方法对铆钉镀层脱落的原因进行分析,并依据表面成分分析、附着力及循环腐蚀试验结果,对铆钉镀层进行了重新开发,为铆钉镀层的选型工作提供借鉴。The certain poor adhesion of SRR rivet coating occurred on aluminum hood in automotive OEM was studied. The causes for the falling of the rivet coating were analyzed by microscopic observation and comparative analysis,etc. Based on the results of surface composition amalysis,adhesion force and cyclic corrosion test,the rivet coating was redeveloped,which provided references for the selection of rivet coating.

关 键 词：铆钉镀层 自冲铆接(SPR) 耐蚀性 附着力
