A kind of preparation method of feconicumo high entropy alloy film

Abstract

The invention discloses a preparation method of a FeCoNiCuMo high-entropy alloy film. Deionized water serves as solvent to be prepared into electroplate liquid, and the electroplate liquid is preparedby an electrochemical deposition method. The method comprises the steps that S1, three parts of deionized water is fetched, triethanolamine, ammonium molybdate tetrahydrate and copper salt are dissolved in the first part of deionized water, and a solution A is obtained; S2, glycocoll, ethanediol, antioxidant and additional salt are dissolved in the second part of deionized water, and a solution Bis obtained; S3, trisodium citrate, bivalent iron salt, cobalt salt and nickel salt are dissolved in the third part of deionized water, and a solution C is obtained; S4, the solution A, the solutionB and the solution C are mixed evenly and aged, the pH value of the mixture is adjusted to be 7-8, the mixture is heated to 30 DEG C, oxygen is removed by leading in nitrogen, and the electroplate liquid is obtained; and S5, a graphite plate serves as an anode and a copper base serves as a cathode for electroplating, and the FeCoNiCuMo high-entropy alloy film is obtained. The method has the characteristics of being simple in equipment and process, high in production efficiency, low in production cost, high in safety and reliability, and the like, and is suitable for industrial production of the high-entropy alloy film.

Description

technical field

[0001] The invention relates to the technical field of novel alloy thin film materials, in particular to a method for preparing a FeCoNiCuMo high-entropy alloy thin film. Background technique

[0002] High-entropy alloys are solid solution phase alloys alloyed by more than five elemental components in an equiatomic or nearly equiatomic ratio. High-entropy alloys have some excellent properties that cannot be compared with traditional alloy materials, such as high strength, high hardness, high wear resistance, high corrosion resistance, high thermal resistance, high electrical resistance, etc., making them have high application value in the field of materials science And prospects, together with bulk amorphous and composite materials, are called the three hotspots with the most potential for development in the next few decades. Attaching the high-entropy alloy to the surface of the substrate to form a thin film will also exhibit the same performance as the hig...
