AlCrFeNi High-Entropy Coating Fabricated by Mechanical Alloying and Hot Pressing Sintering

Abstract:

The AlCrFeNi high entropy coating was successfully prepared by mechanical alloying and vacuum hot pressing sintering technique on Q235 steel substrate, and the microstructures and microhardness, wear resistance and corrosion resistance were characterized in detail. Results showed that single body-centered cubic solid solution phase appears when the blended powder is ball milled for 30 h. The vacuum hot pressing sintered AlCrFeNi high entropy coating with single BCC solid solution is about 500 μm in thickness, which metallurgically bonded to substrate. The microhardness of the AlCrFeNi high entropy coating is about 520 HV, more than three times larger than that of the substrate. The wear resistance and corrosion resistance of the coating in 3.5% NaCl solution are greatly improved compared with the substrate, showing a dramatic reduction in average corrosion rate and wider passive range.
