The conductivity mechanism of electrical contact surface of tin and tin alloy deposit was introduced and the protection of electrical contact lubrication protective agent for tin deposit under static force and fretting was analyzed. The test results showed that the lubrication protective agent can resist oxidation corrosion and reduce wear.%介绍了锡及锡合金镀层电接触表面的导电机理,分析了电接触润滑保护剂对锡镀层在静态压力及微动情况下的保护作用.试验结果表明,润滑保护剂可以起到抗氧化腐蚀和减少磨损的作用.
