摘　　要：　为了提高高硅铝铸件表面电镀层与基体的结合强度,对镀前浸锌溶液进行了改进和优化,并用电化学测试技术探讨了浸锌时间对电位的影响,结果表明,经过二次浸锌能保证镀层与高硅铝铸件基体之间良好的结合强度。To improve the adhesion of electrodeposit and substrate of high Si-Al casting, pretreatment of zinc dipping solution is modified and optimized, and electrical testing technology is taken to analyze the influences of zinc dipping time on potential. It is turned out that under the zinc dipping condition proposed in this paper, high adhesion been has obtained between electrodeposit and substrate.
