The method comprises the steps:firstly, choline chloride, levulinic acid and distilled water are stirred at a constant temperature to obtain a transparent eutectic solvent; then, ferrous chloride, cobalt chloride hexahydrate, nickel chloride hexahydrate, copper chloride dehydrate and stannous chloride dehydrate are added into the eutectic solvent, and stirring is performed at a constant temperature to obtain an electroplating solution; and graphite serves as an anode, a brass sheet and the like serve as a cathode, the graphite and the brass sheet and the like are immersed into the electroplating solution for constant-current electroplating. The electroplating process is safe, non-toxic, environmentally friendly and economical, and the technical problem that the FeCoNiCuSn high-entropy alloy is difficult to co-deposit is solved.

Description

technical field [0001] The invention belongs to the technical field of electroplating, and in particular relates to a method for preparing FeCoNiCuSn high-entropy alloy by electrodeposition. Background technique [0002] High-entropy alloys are simple solid solutions of five or more elements. At the beginning, it was found that alloys composed of more principal elements would have complex microstructures and unsatisfactory brittleness. However, Yeh proposed in 1995 that the alloy system containing five or more metal elements actually has a higher mixing entropy, which is conducive to the formation of multiple solid solution phases. In addition to high-entropy effects, the formation of solid-solution phases is also attributed to the large lattice distortion and slow diffusion of this multi-element mixture. Depending on their composition or processing technology, high-entropy alloys exhibit different microstructures and properties. Among them, the high-entropy alloy coating...
