Microstructure, Mechanical Properties, Wear and Erosion Performance of a Novel High Entropy Nitride (AlCrTiMoV)N Coating Produced by Cathodic Arc Evaporation

(AlCrTiMoV)N high entropy nitride film was prepared on 17-4PH stainless steel substrate using cathodic arc evaporation (CAE). The composition, microstructure, and thermal stability were investigated scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD). Mechanical properties such as hardness Young’s modulus coating performance against wear erosion also evaluated. results show that the assumes a single-phased solid solution B1 FCC structure. It has excellent retains its structure with no decomposition observed up to temperature of 1000 °C. elastic are measured 21.3 GPa 304 GPa, respectively. contains some metallic droplets. As potential protective coating, lower rate but higher when compared TiN baseline coating.
