Microstructure and Oxidation Resistance of Cr1-xAlxN Coating
A series of Cr1-xAlxN coatings were deposited by reactive magnetron sputtering. The content, microstructure and surface morphology of the coatings were characterized by energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effect of Al content on the microstructure, and the oxidation resistance and hardness was studied. It was found that Cr1-xAlxN compound coating exhibits a cubic structure with (1 1 1) preferred orientations. The oxidation resistance obviously improves with the increase of Al content.
