摘要

实验表明,锡与自身结合,以及与金、钯或银结合,易受微动腐蚀。降解速率取决于所接触的金属以及润滑的状态和类型。在清洁和润滑状态下,锡制金和锡制钯的降解都比锡制锡严重。锡制银的性能略好于锡制锡。抗微动接触润滑剂配方优于抗磨损接触润滑剂。一种专有配方被证明在稳定锡对锡和锡对银组合的接触电阻方面非常有效。然而,锡-金和锡-钯界面的接触电阻增加(约为初始值的五倍)表明,在可能发生微动反应的环境中,不应鼓励这种组合用于关键电路应用。

Mateability of tin to gold, palladium, and silver
It is shown experimentally that tin in combination with itself, as well as with gold, palladium, or silver is susceptible to fretting corrosion. Rates of degradation depend upon the metals in contact and upon the state and type of lubrication. In both the clean and lubricated state, the degradation of tin-to-gold and tin-to-palladium would be considered worse than tin-to-tin. The performance of tin-to-silver is slightly better than tin-to-tin. Antifretting contact lubricant formulations are preferred to antiwear contact lubricants. A proprietary formulation is shown to be very effective in stabilizing contact resistance for the tin-to-tin and tin-to-silver combinations. However, increases in contact resistance (on the order of five times the initial values) for the tin-to-gold and tin-to-palladium interfaces demonstrate that such combinations should not be encouraged for critical circuit applications in environments where fretting reactions are likely.<>
