Abstract

Abstract: Clad coating of mechanical alloyed Ni₆Cr₄W_1.5Fe₉Ti high-entropy alloy powder was prepared by laser melting deposition. The effect of mechanical alloying time on microstructure and corrosion resistance of the coating was studied. The results show that the increase of mechanical alloying time can promote the homogenization of alloy powder composition, the densification of coating and the grain refinement of microstructure. After mechanical alloying rod grinding for 4 h, the components of high-entropy alloy powder are evenly distributed, and the FCC+BCC two-phase solid solution structure is formed. After laser melting deposition, the structure of two-phase solid solution is transformed into FCC single-phase solid solution, which is mainly composed of 4-6 μm equiaxed crystals and a small amount of cellular crystals. Among them, the coating prepared by powder mechanical alloying rod grinding for 4 h has the highest density, hardness and the best corrosion resistance, and its corrosion resistance is nearly two orders of magnitude higher than that of the coating prepared by powder mechanical alloying rod grinding for 0 h.

Key words: mechanical alloying, high-entropy alloy, laser melting deposition, microstructure, corrosion resistance
