摘　　要：探讨温控器装置中的银镍合金在有机缓蚀剂保护下不同装配工况接触电阻的变化情况,研究了两类有机缓蚀剂及组合表现的差异性,通过分析其差异性筛选出PMTA+BTA组合的缓蚀剂对银合金表面的膜电阻的保护有较大的实用价值。This paper discusses the change of contact resistance of silver nickel alloy in temperature controller under the protection of organic corrosion inhibitor under different assembly conditions,studies the differences of two kinds of organic corrosion inhibitors and their combinations,and through the analysis of their differences,it is selected that the PMTA+BTA combination of corrosion inhibitors has great practical value for the protection of film resistance on the surface of silver alloy.
