Abstract

The application of the present invention discloses a production method of tin-plated nickel powder, which comprises the following steps: 1) adding the nickel powder into an organic acid solution containing a surface cleaning agent for cleaning, filtering out the solvent and cleaning it for use; Mixture, dispersant, and tin salt are dissolved in water and alcohol to obtain a tin salt solution; 3) Add the cleaned nickel powder to the tin salt solution, ultrasonically disperse, mix evenly, and obtain a reaction stock solution; 4) add the reducing agent The solution is added into the reaction stock solution for reaction; 5) After the reaction is completed, the tin-plated nickel powder is obtained by filtering, washing, drying and heat treatment. The production method obtains tin-plated nickel powder uniformly coated with a tin layer on the surface of the nickel powder, and the nickel powder formed after heat treatment 3 sn 4 The alloy is in close contact with the nickel substrate and the tin layer has a dense structure, and the nickel-based tin-plated composite material has excellent electrical conductivity and mechanical properties.

Description

technical field [0001] The invention relates to the field of metal powder materials, in particular to a production method of tin-plated nickel powder. Background technique [0002] With the advancement of science and technology, metal materials have new functional requirements in terms of light, electricity, magnetism, thermodynamics and chemical reactions. Many traditional metal powder materials (such as iron powder, nickel powder, zinc powder, silver powder, copper powder, etc.) Powder) used alone or in combination is difficult to meet the ever-changing technical requirements. The nanonization of metal materials makes it have unique properties, such as surface effects, volume effects, quantum size effects, and macroscopic quantum effects, which are different from ordinary metal materials in terms of light, electricity, magnetism, thermodynamics, and chemical reactions. special performance. However, nano-metal powder materials have a large specific surface area, high surf...
