“…Difficulties in the formation and movement of dislocations in the crystal lattice, for example stopping their movement at the grain boundaries may increase hardness of material [21]. The hardness investigated is significantly higher than presented by da Silva Oliveira et al [13]. The similar trend was observed by Vaz et al for TiON [21] and ZrON [18].…”

“…The formation of metal-oxygen ionic bonds present in the matrix of the metal-nitrogen covalent bond occurs even for a small oxygenconcentration in the presence of a growing metal nitride layer. The best known compounds are TiO x N y and ZrO x N y , which have different colors associated with oxygen content [ 6 , 13 , 14 ]. The color ranges from golden yellow with low oxygen to dark blue with high oxygen content [ 1 , 13 ].…”

The transition metal oxynitrides are a coating material with decorative features due to their adjustable color and good mechanical properties. The purpose of the research was to study the effect of the relative oxygen concentration O2(x) = O2/(N2 + O2) in particular on adhesion, but also on the color, structural and mechanical properties of ZrON coatings synthesized by cathodic arc evaporation on HS6-5-2 steel substrates. The surface morphology, phase and chemical composition and mechanical properties were determined using scanning electron microscopy, X-ray diffraction, wavelength dispersive X-ray spectroscopy, nanoindentation and scratch test. It was found that color of the coatings changed from light yellow for ZrN first to gold and then to graphite for Zr-O phase with increase of oxygen concentration. X-ray diffraction patterns showed that the phase separation of ZrN and ZrO2 occurred for about 35 at.% of oxygen in the coating. Increase in oxygen concentration in the coatings led to decrease in crystallite size from about 20 nm for ZrN to about 5 nm for coatings with about 35 at.% of oxygen and about 25 at.% of nitrogen. An increase in hardness from about 26 GPa for ZrN to about 30 GPa for coating with small concentration of oxygen (about 9 at.%) and then decrease to about 15 GPa was observed. Adhesion of Zr-O-N coatings demonstrated strong dependence on oxygen concentration. Critical load for ZrN is about 80 N and decreases with oxygen concentration increase to about 30 N for ZrO2.

“…In addition, a combination of transitional metal nitrides and oxides as oxynitrides promises the possibility to tune the structural, optical and electrical properties in a wide range as desired for various applications, like hard coatings, decorative coatings as well as solar devices. See for example, some works on these TiO x N y [7,8] , ZrO x N y [9,10,11] , TaO x N y [12] films.…”

Zirconium nitride films are deposited onto stainless steel AISI 316L and silicon (100) by radio frequency magnetron sputtering at different nitrogen flow ratios [N2/(Ar+N2)] varied between 0 and 0.25). Scanning electron microscope, atomic force microscopy, X‐ray diffraction (XRD), and Raman are used to investigate the surface morphology and microstructure of the thin films. The mechanical and electrochemical properties of all coatings are evaluated and compared with the uncoated AISI 316L to explore the efficiency of surface modification. The XRD and Raman analysis show that all the films are crystalline. This shows that the increased nitrogen content leads to a transformation from hexagonal α‐Zr phase to cubic c‐Zr and then to mixed α‐Zr and face centered cubic c‐ZrN phases. The films deposited with nitrogen flow ratio of 0.2 show the highest hardness of 32.2 GPa. Using the potentiodynamic polarization method, the corrosion behavior of the films is studied in Hank's solution. The comparison between uncoated and coated substrates shows a decrease in corrosion current density for all coated samples.
