Abstract : Surface work hardening of C 0.38-0.50 percent steel makes it possible not only to raise the fatigue strength but also the wear resistance of parts operating in conditions of cyclic overloading and wear. The positive effect of surface cold work is particularly significant for friction with lubricant. MoS2 applied to degreased surfaces by depressed rollers raises the wear resistance of steel parts and noticeably decreases the frictional wear in couples with bronze during friction in an oil environment.
