Abstract

Composite (CrAl)N and (CrAlSi)N hard coatings were deposited on 1Cr11Ni2W2MoV steel sheets by arc ion plating system under different N2 partial pressure (1Pa, 2Pa or 4Pa) respectively. The composition, microstructure, phase composition and oxidation resistance were characterized by SEM, EDS and XRD. With the N2 partial pressure increasing from 1Pa to 4Pa, (CrAl)N kept its B1 structure and the (CrAlSi)N changed the phase structure from blends of B1 and B4 to single B4, the content of Al and Si decreased slightly, and the density of droplets decreased and the stuctrue density improved. Oxidation experiments at 900oC show that increased of N2 partial pressure and the introduction of Si into the (CrAl)N can block the phase seperationg and increase the oxidation resistance of the coatings.
