Three coatings of decorative chromium, hard chromium, and zinc electrolytically deposited on the C45 steel substrate are considered. The experimental characterization of the tribological response of the substrate and different coatings against a spherical 100Cr6 counterbody is developed with the help of a linear reciprocating tribometer. The results show that the indicated three coatings have similar values for the stabilized friction coefficient that remains much higher than the value of the friction coefficient for the substrate. The decorative chromium coating has the lowest wear resistance. A better wear resistance is obtained for the zinc coating. The first place in terms of the wear resistance is occupied by the hard chromium coating and the uncoated substrate which have a similar resistance.
