Abstract
AbstractThis work focuses on the effect of different mass ratios of WC (5 wt%, 10 wt%, 15 wt%, 20 wt%) on the structure and properties of the CrMnFeCoNi high-entropy alloy-deposited layer prepared by PTA. The SEM, XRD, and EDS were used to characterize the coatings. The XRD analysis shows that the addition of ceramic phase WC does not change the face-centered cubic structure of the high-entropy alloy coatings. The EDS analysis shows that the five main components of the high-entropy alloy coatings are distributed uniformly inside the coating, while the W element is mainly distributed in the intercrystalline area or deposited on the bottom of the coating in the form of unmelted WC particles. The mechanical test results show that the addition of WC can effectively improve the hardness and wear resistance of the coatings. The electrochemical results show that the addition of WC greatly improves the corrosion resistance of the coatings.Graphical abstract
