CoCrFeNi(W1 − xMox) high-entropy alloy coatings with excellent mechanical properties and corrosion resistance prepared by mechanical alloying and hot pressing sintering
Mechanically alloyed CoCrFeNi(W1 − xMox) coating powders are mixture of BCC/FCC phases. High-quality HEA coatings (HEACs) were fabricated on Q235 via hot pressing sintering. HEACs exhibit good metallurgical bonding to Q235 and uniformly distributed grains. CoCrFeNiW HEAC has the better HV and wear resistance compared to Mo addition. Corrosion resistance in 3.5% NaCl for HEACs is greatly improved than Q235.
