Abstract
In this study, the CrN coating was first deposited on tool steels by cathodic arc evaporation
technique and then this coating was subjected to oxygen glow discharge to activate the oxidation
process in order to form oxide layer on the surface of the CrN coating. The varied properties of CrN
coatings with or without oxidation treatment were studied in terms of hardness, adhesion,
microstructure and surface morphology by using XRD, AFM, Rockwell indentation,
Nano-indentation tests. The result turned out that the effect of the plasma oxidation process on the
hardness of CrN coating was improved due to the oxide layer on the surface.
