“…It can be seen from Figure 17a-c that the wear mechanism of the HEA gradually changed from adhesive wear to abrasive wear with the increase of WC content from 0 to 20%. This is consistent with Xu's results [35]. Abrasive wear easily accelerates the wear rate in local areas.…”

“…However, some scholars have proposed that excessive WC would have an opposite effect on wear resistance. Xu and coworkers [35] found, in their study of WC-CrMnFeCoNi coatings, that excessive WC may cause excessive abrasive wear, leading to an increase in the friction coefficient of the coating. In addition, excessive WC causes the aggregation of carbides, accelerating the dissolution and corrosion of the coating.…”

In recent years, high entropy alloy (HEA) matrix composites have undergone rapid development. In this work, the effects of different WC contents (10 wt.%, 20 wt.%, and 30 wt.%) on the microstructure, mechanical properties, and wear resistance of FeCoCrNi HEA matrix composites prepared by spark plasma sintering (SPS) were studied. The results show that the WC–HEA composites are mainly composed of an FCC matrix phase (Ni, Fe) and carbide phases (Cr7C3, Co3W3C, WC, etc.). The hardness of the 30 WC–HEA composites was the highest at 459.2 HV, which is 71.2% higher than the 268.3 HV of the pure matrix material. Similarly, the compressive yield strength of the 30 WC–HEA composite was the largest, reaching 1315.1 MPa, which is 112.1% higher than that of the pure matrix material. However, the compression deformation rate of the 30 WC–HEA composite significantly decreased to 16.6%. Under the same dry friction conditions, the addition of an appropriate amount of WC particles can reduce the friction coefficient of the HEA matrix. The wear volume of the composites decreased rapidly with the increase of WC content. The wear volume of 30 WC–HEA was the lowest, only 3.17% of that of the pure matrix material.

“…High-speed laser cladding has the lowest overall heat input and the fastest cooling rate of the coating, so the grain size of HLC is slightly smaller than that of DLC and PC. energy cladding [27]. The complete change in the crystal structure of DLC may be related to the high dilution ratio of the coating.…”

Three kinds of Fe30Ni20Co20Cr20Mo3.5 high entropy alloy (HEA) coatings were prepared on the surface of a Q235 steel plate using plasma cladding and laser cladding. The microstructure, crystal structure, element distribution, microhardness, wear resistance, and corrosion resistance of the coatings were studied. The grain size of the high-speed laser cladding coating (HLC) was the smallest. The crystal structures of the plasma cladding coating (PC) and HLC were single face-centered cubic (FCC), while that of the deep laser cladding coating (DLC) was body-centered cubic (BCC). DLC had the best microhardness and wear resistance. The microhardness of PC, HLC, and DLC increased by 70%, 108%, and 109%, respectively, and the average friction coefficient decreased by 33%, 44%, and 51%, respectively, compared to Q235. HLC had the best corrosion resistance, with an annual corrosion rate of 0.66925 mm/a. The annual corrosion rate of PC and HLC was only 40% of Q235. The polarization curves of PC and HLC had obvious passivation regions with a width of up to 2 V. The corrosion types of PC were pitting corrosion and intergranular corrosion, that of HLC was general corrosion, and that of DLC was severe pitting corrosion.

“…High-entropy alloys (HEAs): The main feature of HEAs is that they provide the possibility of creating extraordinary properties by combining several different elements [87][88][89][90]. The use of HEAs as a binder in tungsten carbide compounds simultaneously increases the hardness and toughness of the product, and consequently can be a new and versatile binder compared to cobalt [5,[91][92][93][94]. Regarding the attention which has been drawn to this type of binder in recent years, few articles with HEA binders have studied oxidation properties [3,95,96].…”

This study presents a conceptual classification scheme to review the literature on improving the oxidation resistance of tungsten carbide by modifying the binder. The first parts of the article are dedicated to the specification of the databases, the search method, and the description of the criteria chosen to classify the articles. Then, the data collected are presented in statistical graphs according to the proposed classification scheme. The data analyzed show that most of the significant improvements in oxidation resistance are achieved with advanced production processes, especially HIP and SPS, which eliminate porosity to a very high degree. In addition, statistical studies showed that the use of new replacement binders, Ni3Al, Fe–based alloys, FeAl, and Al2O3, improved the oxidation properties in 75–100% of cases. Meanwhile, the use of high–entropy alloys (HEAs) as cermet binders may be the subject of future research for oxidation, given the recently published results of good mechanical properties.
