Method for plating copper and copper alloy coiled material with nickel

Abstract

The invention discloses a method for plating a copper and copper alloy coiled material with nickel. After the coiled material is unfolded, the method sequentially comprises the following continuous steps that 1, the surface of the coiled material is subjected to degreasing and oil removing; 2, the surface of the coiled material is subjected to acid pickling; 3, the surface of the coiled material subjected to acid pickling is electroplated with a nickel layer, wherein the coiled material is adopted as a cathode, a nickel ball is adopted as an anode, the coiled material is soaked in a mixed solution including nickel aminosulfonate, nickel chloride, boric acid, a nickel softening agent, a nickel brightener and a phosphorus containing additive, and cleaning is carried out with purified water one or more times; 4, a purifying process is carried out, wherein the nickel layer is protected; 5, coating treatment is carried out, wherein micropores in the surface of the nickel layer are blocked off through organic matter; and 6, the coiled material is blown and dried. According to the method, a continuous electroplating process,of the copper and copper alloy coiled material, namely, a processof electroplating the copper coiled material with nickel is achieved, and the matte or bright, dense, uniform and continuous clad layer firm in combination is formed on the surface of the copper material. The electroplated surface of the copper material has the characteristic of nickel, and meanwhile the beneficial effects of the copper materials are achieved.

Description

technical field [0001] The invention relates to a method for plating nickel on a metal substrate, in particular to a method for plating nickel on copper and copper alloy coils, and belongs to the technical field of metal surface processing. Background technique [0002] The electroplating process is the process of plating a thin layer of other metals or alloys on the metal surface using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation (such as Rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance and enhance the appearance. [0003] The traditional electroplating production method is: first find material manufacturers to purchase materials, then go to stamping and forming, then electroplating, and finally return to users. This method adds additional intermediate links, transportation costs, time costs, etc. As ...

Problems solved by technology

As the production process of electronic products becomes more and more mature, the requirements for suppliers are also getting higher and higher. When the products need to be welded, the weight of the single chip is lighter, and the production speed is faster, the traditional production methods can no longer meet the needs of customers. Require

[0004] The traditional electroplating method cannot overcome the continuous electroplating process of coils. Although there are continuous electroplating production processes in the market, the process of electroplating nickel on copper alloy coils is not yet mature. Therefore, in order to realize continuous electroplating of coils The process still needs to overcome technical difficulties
