EFFECT OF BORON ISING ON FRICTION

Summary Boronising is a surface diffusion treatment analogous to carburising, but produces harder surfaces without recourse to quenching. Friction and wear resistance of boronised coatings have been evaluated on steels and "grey cast iron under dry sliding conditions. Boronising inhibits adhesive wear during running-in and at loads above the mild/severe transition load. The onset of severe wear is prevented until the boronised layer has been worn away, its life expectancy is extremely long and is inversely related toapplied load. TE 99 通用摩擦磨损试验机
