“…Larijani et al., [ 32 ] studied the effect of texture on the electrochemical properties of ZrN coatings and found that corrosion resistance increased when the preferential orientation of the coating is (111). This protection is related to the compact structure of the film ZrN (111) and to its lowest energy and therefore to its improved chemical stability.…”

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.

“…It has been known for decades that Zr x N y films exhibit good anticorrosive properties, [11][12][13] and some general study of comparison of nitride materials has been done. [14] Recently, Zr x N y and zirconium oxynitride (Zr x N y O z ) films have been synthesized on different substrates using various techniques such as magnetron sputtering, [4,[15][16][17][18] ion nitriding, plasma immersion ion implantation and deposition, [19] ion beam sputtering, [20,21] cathodic arc deposition, [5,22] plasma electrolytic oxidation, [23] and multiarc ion plating. [24] Zr x N y O z has lately received attention due to its unique properties tuned by the admixture of nitrogen and oxygen during the Herein, highly crystalline Zr x N y and Zr x N y O z coatings are achieved by the deposition via high-power impulse magnetron sputtering.…”

Herein, highly crystalline ZrxNy and ZrxNyOz coatings are achieved by the deposition via high‐power impulse magnetron sputtering. Various N2 and N2/O2 gas mixtures with argon are investigated. The chemical composition and, as a result, mechanical properties of the deposited layer can be tailored along with morphological and crystallographic structural changes. The corrosion resistance behavior is studied by potentiodynamic measurements and electrochemical impedance spectroscopy in a sample of synthetic wastewater designed to imitate real‐life domestic wastewater. The corrosion current density of the ZrxNyOz coating is in the range of 33–70 μA cm−2, whereas for the zirconium nitride layers, values below 1.0 μA cm−2 are achieved. The highest corrosion resistance of 64 nm year−1 is observed for the ZrxNy coating deposited with 1.00% N2 content in the gas mixture with a corrosion potential of −0.41 V Ag/AgCl.

“…Nitrides of transition metals such as TiN [1], ZrN [2], MoN [3], CrN [4], TiAlN [5] and TiZrSiN [6] are widely used as protective coatings for cutting tools, parts and mechanisms of various functional purpose because of their high hardness and wear resistance [7,8]. In addition, coatings such as CrN also have a high resistance to oxidation, wear and corrosion [9,10].…”

The influence of the layers thickness of bilayer multi-period coatings of the CrNx/MoNx and CrNx/TiNx systems on their phase-structural state, substructure, stress-strain state and mechanical properties was studied using methods of precision structural analysis in combination with computer simulation of implantation processes during particle deposition. It is established that a two-phase structure of CrN and -Mo2N phases of the structural type NaCl is formed in the multi-period coatings of the CrNx/MoNx system with a nanometer thickness of the layers. Because of the small difference in periods (less than 0.5 %) for Λ  20 nm, the layers form a coherent interlayer interface. The use of small Ub -20 V during deposition makes it possible to avoid significant mixing at interlayer (interphase) boundaries even at the smallest Λ  10 nm. Nitride layers formed under conditions of vacuum arc deposition are under the action of compressive stresses. In the СrNх/TiNх system, because of the relatively large discrepancy between periods (more than 2.5 %), during the formation of the same structural components in the layers (CrN and TiN phases of the structural type NaCl), the epitaxial growth with period adjusting does not occur, even for the smallest Λ  10 nm. The action of the deformation factor at the interphase boundary allows achieving an ultrahard state (with a hardness of about 50 GPa), which causes a relatively low friction coefficient. The obtained results on the formation of phase-structural states with the nanoscale thickness of layers of multi-period nitride coatings are explained from the position of minimization of surface energy and deformation energy.
