A SUMMARY ON P/M FRICTION MATERIALS

The present paper breifly summarizes the composition test of P/M friction materials for increasing and stabilizing friction coefficent, improving wear-, heat-, and corrosion-resistance and magnetic conductivity and saving production costs. The properties of P/M friction material are also summarized. Varions processes for manufacturing P/M friction materials,including methods being in use and under test are described. Finally, some evaluations on prospects of P/M friction materials are outlined.
