ANTIWEAR PROPERTIES OF MEDIUM-CARBON STEEL WITH Cr/CrN TYPE HYBRID COATING PRODUCED BY THE PVD METHOD
Journal Title: Tribologia - Year 2018, Vol 282, Issue 6
Abstract
The paper presents the results of examinations of the structure, and mechanical and antiwear properties of hybrid coatings of the Cr/CrN type, consisting of chromium and chromium nitride, formed on the surface of the C45 medium-carbon steel by the Arc-PVD method. Investigations of the morphology and microstructure of hybrid coatings, as well as of their phase composition were carried out. The studies on mechanical properties included tests on hardness and Young’s modulus using the nanoindentation method. Tests on adhesion were conducted using the scratch-test. Tribological properties (linear wear) of the coatings were performed by means of taper-three rolls test. The investigations showed that the linear wear of the C45 steel samples with the Cr/CrN hybrid coatings is 7–9 times smaller than that of hardened steel samples without any coatings. This indicates the excellent tribological properties of the C45 medium-carbon steel with the Cr/CrN type hybrid coatings deposited by the Arc-PVD method.<br/><br/>
