Microstructure and Properties of CrN Multilayer Coatings

Abstract:

The CrN and Cr/CrN multilayer coatings with different modulation ratios were deposited onto stainless steel and cemented carbide substrates by arc ion plating technology. The phase composition, surface and cross-sectional morphology were analyzed by using X-ray diffraction (XRD), atomic force microscope (AFM) and scanning electron microscope (SEM). The micro Vickers was used to test the hardness. The results indicated that the coatings were mainly composed of Cr, CrN and Cr2N phase. No columnar grain growth was observed in Cr/CrN multilayer coatings, and the crystalline orientation of the Cr/CrN multilayer was different from CrN film. There exists an optimal modulation ratio of 10:10 to the coating deposition, under which the surface was compact and smooth with a relatively lower roughness. The coatings hardness increased with decreasing modulation ratio and the hardness of CrN+Cr2N was lower than that of single CrN phase.
