Electrical contacts are usually plated in order to prevent corrosion. Platings of detachable electrical contacts experience wear\r\nbecause of the motion between contacts. Once the protecting platings have been worn out, electrical contacts will fail rapidly due to\r\ncorrosion or fretting corrosion. Therefore the wear resistance of the platings is a very important parameter for the long lifetime of\r\nelectrical contacts.Many measures which improve the wear resistance can diminish the conductivity of the platings. Due to the fact\r\nthat platings of electrical contacts must have both a high wear resistance and a high electrical conductivity, the manufacturing of\r\nhigh performance platings of electrical contacts poses a great challenge. Our study shows firstly the correlation between the wear\r\nresistance of platings and lifetime of electrical contacts and then the measures, which improve the wear resistance without impairing\r\nthe electrical performance of the contacts.
