ABSTRACT:
A method for depositing a composite coating on a substrate is provided. The coating contains a mixture of ductile metal particles and a uniformly dispersed polymer particles. The polymer is present in a concentration effective to reduce frictional forces. The coating mixture is compacted such as by isostatic pressing, formed into strips and then clad to the substrate. One preferred coating contains 0.5 weight percent polytetrafluoro-ethylene in a tin matrix.
