“…to form nano-composite and single-phase (solid solution) coatings. Recently, many studies have suggested that alloying a small amount of yttrium to TiN-based coatings, 14,15 CrN-based coatings 16,17 and ZrN-based coatings 18,19 could improve the oxidation resistance. For instance, Xu et al 20 have prepared the Ti-Y-N coatings and investigated the effect of yttrium addition on the oxidation resistance.…”

W-Y-N coatings with yttrium content ranging from 0 to 8.2 at.-% were deposited by reactive magnetron sputtering technique. The influence of yttrium content on the structure, oxidation resistance and mechanical properties was investigated. The results show that yttrium atoms substitute tungsten atoms forming the solid solution W-Y-N coatings. All the coatings exhibit a single-phase face-centered cubic structure and the preferred orientation changes from ( 200) to ( 111) with yttrium addition. The grain size of W-Y-N coatings decreases with the increase of yttrium content. The oxidation resistance temperature of W-Y-N coatings increases from 500°C at 0 at.-% Y to 730°C at 8.2 at.-% Y. All coatings are in compressive stress state. The hardness, elastic modulus and compressive stress of W-Y-N coatings increase gradually from 28.0, 320 and 1.1 GPa at 0 at.-% Y to 36.0, 385 and 2.1 GPa at 8.2 at.% Y, respectively. The improvement of hardness was attributed to the effect of solid solution strengthening and the grain refinement. In addition, the addition of yttrium content into WN coating also improves its resistance against elastic strain and plastic deformation to failure.

“…The Gibbs free energy changes corresponding to these reactions are as follows [28]: Figure 8 shows the surface morphology of coating A, as deposited and oxidized at different temperatures. Figure 8a shows a relatively smooth surface with some microparticles or droplets, which are typical for arc evaporated coatings [29,30]. After oxidation at 500°C, the microparticles did not change much, but on the former smooth surface, a meshwork of lighter line becomes visible.…”

AbstractChromium nitride coatings prepared by physical vapour deposition (PVD) show high hardness, high strength and good thermal conductivity, which makes them useful for cutting and forming tools. In this article, the microstructure and corrosion resistance of multilayer Cr/CrN coatings deposited by arc evaporation and hybrid high power impulse magnetron sputtering (hybrid HIPIMS) after oxidation between 500 and 800°C were examined. The average thickness of the coatings was about 3.5 µm. By means of the surface morphology analysis, elemental energy spectrometry and potentiodynamic polarization tests, the performances of the two groups of coatings have been compared. The results revealed that the coating deposited by the hybrid HIPIMS has stronger binding force with substrate, fewer surface defects and a denser structure. Also, the hybrid HIPIMS coatings have a better oxidation resistance and a better corrosion resistance compared to the arc evaporated coatings.

“…The addition of Y to the CrN coating could effectively refine grains, improve the coating structure, and improve the mechanical and friction properties of the coatings [18,19]. Wu et al [20] prepared a CrYN coating using a reaction co-sputtering method and found that Y ions replaced Cr ions in the Cr-N lattice to form a solid solution Cr1-xYxN coating, increasing hardness from 12. 9 to 13.7 GPa and improved the adhesion of the coating.…”

CrYN, TiBN, and CrYN/TiBN coatings were successfully deposited on 316 stainless steel substrates via multi-arc ion plating techniques to improve their wear and corrosion resistance properties in marine environments. The morphology, microstructure, friction performance, and corrosion resistance of the three coatings in artificial seawater were systematically studied. X-ray diffraction, X-ray photoelectron spectroscopy, and scanning electron microscopy investigations confirmed a dominant face-centered cubic CrN structure, accompanied by hexagonal TiB2 and amorphous BN in CrYN/TiBN coatings. The SEM cross-section shows that the TiBN and CrYN/TiBN coatings have a more compact cross-sectional structure than the CrYN monolayer coating. The CrYN/TiBN coatings exhibited the lowest smooth friction coefficient in artificial seawater, and the wear rate was ranked as TiBN<CrYN/TiBN<CrYN. Surface morphological studies performed after tribocorrosion revealed that the protection ability of all three coatings remained acceptable. The electrochemical test showed that the corrosion tendency was CrYN/TiBN<TiBN<CrYN, and the CrYN/TiBN coating had the best performance in the AC impedance spectrum and polarization curve.
