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...
