In this work the tribological properties of coatings molybdenum, chromium, and stellite B3K obtained by electrospark alloying method on 45steel were studied. Tests data with rollers made of steel C45 HRC 50-52 and steel 30CrMnSiA HRC 38-42 showed, that molybdenum coatings were the most wear resistant. Tests with rollers made of steel 30Cr13 HRC 43-45 showed that wear resistant of chromium coatings was highest. During the work with rollers made of steel C45 and steel 30CrMnSiA, the molybdenum coatings were the most antifriction ones - at the beginning friction coefficient was f = 0.12-0.11, and at the end f = 0.04-0.034. The friction couple that was determined to be the most wear resistant was a block of steel C45 with a chromium coating and roller made of steel 30Cr13 (wear was Ublock = 0.4 mg and Uroller = 10.8 mg).
