<p>A composite coating (16) for electrical connectors (10) is provided. The coating contains a ductile metal matrix and a uniformly dispersed polymer component. The polymer component is present in a concentration effective to reduce frictional forces generated when inserting an insertion component (12) into a socket (14). The composite coating (16) has lower friction and improved fretting corrosion resistance as compared to an electrodeposited tin coating. One preferred coating contains 0.5 weight percent polytetrafluoroethylene in a tin matrix.</p> |
