Problems solved by technology

[0003] Pure nickel foil has a high surface finish, good corrosion resistance and mechanical properties, and is widely used in the fields of magnetic shielding and high energy storage. However, due to the high smoothness of pure nickel foil, a lot of manpower is required for subsequent processing. The surface roughening treatment is carried out by physical force, and most of them are treated by mechanical grinding or two-step chemical treatment. The roughness of the processing is poorly controllable, which also limits the application field of pure nickel foil. Therefore, the development of The process of preparing roughened nickel foil is the main direction to solve the roughening of nickel foil at present.

Embodiment 1

[0020] The specific steps of the process for preparing roughened nickel foil by electrodeposition in this embodiment are as follows:

[0021] 1) Pre-preparation: Use a cutting machine to cut the purchased metal nickel plate anode material into a cuboid plate with a length of 0.3m, a width of 0.04m, and a thickness of 1cm, and then arrange the cut nickel anode materials neatly, and use titanium oxide type Welding with welding rods, and then placing the welded nickel anode material in a dilute sulfuric acid solution with a concentration of 4% for acid activation to remove rust and oil stains on the surface of the nickel metal, which is conducive to improving the uniformity of the product during the electrodeposition process. After the acid treatment, the nickel anode material is washed with water to remove acid, and then dried by air to obtain the activated nickel anode material; the large nickel metal plate purchased is cut, and then welded for electrodeposition, which is conduc...

Abstract

The invention discloses a technology for preparing a coarsened nickel foil with an electrodeposition method and belongs to the technical field of nickel alloy. The technology comprises the following steps of pretreatment: cutting a purchased large metal plate, performing welding and surface decontamination; and electrodeposition: putting a treated nickel anode material in an electrolytic cell forprimary electrodeposition to prepare the coarsened nickel foil. The coarsened nickel foil prepared with primary electrodeposition is good in thickness uniformity, uniform in surface roughness, has theuniformity being 2-3 times the uniformity of the nickel foil coarsened with mechanical grinding and is suitable for thin and wide high-performance soft magnetic foil strip material insistently demanded by the electric and electronic industry.

Description

technical field [0001] The invention belongs to the technical field of nickel alloys, and in particular relates to a process for preparing roughened nickel foil by electrodeposition. Background technique [0002] Electrodeposition refers to the process of electrochemical deposition of metal or alloy from its compound aqueous solution, non-aqueous solution or molten salt. It is the basis of metal electrolytic smelting, electrolytic refining, electroplating, and electroforming processes. These processes are carried out under certain electrolyte and operating conditions. The difficulty of metal electrodeposition and the shape of the deposit are related to the properties of the deposited metal, and also depend on the composition of the electrolyte, pH value, temperature, current density and other factors. Foil prepared by electrodeposition has a one-time process, simple process, low cost, uniform thickness, fine structure, no holes and large grains, and can continuously produce...
