Abstract

The invention relates to a preparation method of a nickel-copper alloy sheet material. The preparation method comprises the following steps: (1) substrate cleaning to remove oil stains and oxide scales so as to enhance the substrate surface activity, and blow-drying for later use; (2) selecting targets; (3) preparing a coated sheet; and (4) dispersing the solid solution. According to the preparation method, the multi-target magnetron sputtering process is utilized to perform continuous sputtering on the multiple targets, and the deposited film can not be easily polluted, and has the advantages of high deposition power and high quality. In the preparation process, the substrate can be cleaned to enhance the adhesion force of the substrate, and after-treatment dispersion is carried out to homogenize the alloy. The method has the advantages of high deposition rate, controllable quality and high work efficiency, does not have the problems of nickel element oxidation, environment pollution, hazards to human safety and the like in the preparation process due to the complete vacuum conditions, and thus, is suitable for industrial popularization.

Description

Technical field [0001] The invention relates to the preparation of an alloy material, in particular to a preparation method of a nickel-copper alloy sheet material. Background technique [0002] Nickel-copper alloy is a typical precipitation-strengthened alloy. It has a series of advantages such as high elasticity, high strength, high conductivity, corrosion resistance, fatigue resistance, small elastic hysteresis, non-magnetic, and no sparks when impacted. It is widely used It has broad application prospects in the aerospace, aviation, electronics, communications, machinery, petroleum, chemical, automotive and home appliance industries. [0003] At present, nickel-copper alloy plate materials are basically prepared by rolling, mainly including semi-continuous casting ingot + milling skin + heating + rough rolling + quenching + secondary rolling + quenching + pickling + brushing + finishing rolling. . As the nickel-copper alloy ingot tends to secondarily segregate during crystall...
