THE LUBRICATING PROPERTIES OF ION-PLATING FILMS OF Pb-Sn ALLOY

Experimental results of the lubricating behaviour of Pb-Sn alloy films formed by ion-plating on brass substrates are given. It is shown that the film microhardness, friction coefficient and wear life per thickness are under the influence of the substrate. The wear failure of film appears to be film adhesion and transferring by the mating surface.
