TRIBOLOGICAL PROPERTIES OF HYBRID LAYERS PRODUCED IN COMBINING THE DIFFUSION CHROMIZING PROCESS AND PVD TREATMENT
Journal Title: Tribologia - Year 2014, Vol 254, Issue 2
Abstract
Tribological properties of the CrC+CrN type hybrid layers, produced on X210Cr12 steel in chromizing process by the pack powder method combined with arc evaporation PVD treatment, have been investigated. A comparison of the CrC+CrN type hybrid layers with the CrC single carbide layers, produced on steel surface without CrN coating, has been performed. Tribological properties of the layers were performed by means of taper-three rolls test. It has been proved that the resistance to abrasive wear of hybrid CrC+CrN type layers is almost two times higher than that for the single CrC carbide layers.
