“…Furthermore, the use of HEA coatings for repairing and remanufacturing can significantly reduce material consumption, achieving energy savings and enabling secondary use of mechanical parts. Methods of preparing HEA coatings include magnetron sputtering [22], thermal spraying [23,24], laser melting [25] and so on. Qiu et al [26] prepared the Al 2 CrFeNiCoCuTix high-entropy alloy coatings through laser cladding and found that the relative wear resistance of the high-entropy alloy coatings was greatly improved with increased titanium content.…”

High-entropy alloys receive more attention for high strength, good ductility as well as good wear resistance. In this work, CoCrFeNiMn high-entropy alloy (HEA) coatings were deposited on compacted graphite iron through plasma transfer arc at different currents. The microstructure and wear properties of the CoCrFeNiMn HEA coatings were investigated. The coatings are composed of single phase with FCC structure. The CoCrFeNiMn HEA coating had the highest microhardness of 394 ± 21.6 HV0.2 and the lowest wear mass loss when the plasma current was 65 A. All of the HEA coatings had higher friction coefficients than that of the substrate. There were adhesive, abrasive and oxidation wear forms in the HEA coatings with the wear couple of N80 alloy. The HEA coating presented higher friction coefficient and better wear resistance than compacted graphite iron.

Cladding-based repair has been found to be superior than welding or flame spraying repair approaches in terms of extending die life. In this work, two different alloy powders, that is, CrNiW and CrNiFeAlZr were coated on H13 steel using laser cladding. The laser power, powder feed rate and scanning speed were varied and the clad dimensions, aspect ratio and dilution percentage were measured. The microhardness found in the CrNiW clad is 834 ± 20 HV0.5, which is higher than that of the CrNiFeAlZr clad (780 ± 20 HV0.5) as well as the substrate clad (548 ± 20 HV0.5). CrNiW clad has a higher microhardness than CrNiFeAlZr clad and substrate, indicating that CrNiW laser cladding has a significant impact on microhardness. The interface region for CrNiFeAlZr has 8.33% of C, which is less than the interface region for CrNiW (10.65% of C) so that the microhardness at the interface in CrNiW clad is high. The XRD patterns identified the common phase creation of Ni3C and Fe3C for CrNiFeAlZr and CrNiW coatings, while the oxide formation was only seen in CrNiFeAlZr coatings and the addition of carbon content in the CrNiW clad layer forms WC, Cr23C6, Ni3C and Fe3C. A response surface methodology with a Box-Behnken design is used in the optimisation process.

High entropy alloy attracts great attention for its high thermal stability and corrosion resistance. A CoCrFeNiMn high-entropy alloy coating was deposited on grey cast iron through plasma transfer arc cladding. It formed fine acicular martensite near the grey cast iron, with columnar grains perpendicular to the interface between the grey cast iron substrate and the cladding layer as well as dendrite in the middle part of the coatings. Simple FCC solid solutions present in the coatings which were similar to the powder’s structure. The coating had a microhardness of 300 ± 21.5 HV0.2 when the cladding current was 80 A for the solid solution strengthening. The HEA coating had the highest corrosion potential of −0.253 V when the plasma current was 60 A, which was much higher than the grey cast iron’s corrosion potential of −0.708 V. Meanwhile, the coating had a much lower corrosion current density of 9.075 × 10−7 mA/cm2 than the grey cast iron’s 2.4825 × 10−6 mA/cm2, which reflected that the CoCrFeNiMn HEA coating had much better corrosion resistance and lower corrosion rate than the grey cast iron for single FCC solid solution phase and a relatively higher concentration of Cr in the grain boundaries than in the grains and this could lead to corrosion protection effects.
