Abstract

Electrical contacts, which are used in aerospace engineering with high reliability requirements, are usually plated in order to prevent corrosion. The wear and fretting corrosion behavior of gold plated copper contacts is studied at different current loads. The degradation of contacts is explained with reference to current to melt metal and breakdown oxide films. The contacts with higher current delay the time before reaching failure. The comparison between the cases with and without current load revealed metal melting as a result of current heating. The observed surface morphology reveals five typical regions within the fretted zone.
