摘　　要：针对高压开关行业用镀银层易变色问题,分别制备了纯银层、银-石墨镀层、银-石墨烯镀层和银-锡合金镀层,并主要对比分析了其抗变色性能等性能。研究结果表明,银-锡合金镀层的抗变色性能明显优于其他三种镀层,故银-锡合金镀层可替代银层,应用于户外高压开关零部件。In view of the problem that silver coating is easy to change color in high-voltage switch industry,pure silver coating,silver graphite coating,silver graphene coating and silver tin alloy coating were prepared respectively,and their anti-tarnish properties were compared and analyzed. The results show that the anti-tarnishing property of the silver-tin alloy coating is the best. Therefore,silver tin alloy coating can replace silver coating and be used in outdoor high-voltage switch parts.
