What is the difference between electroplated nickel and electroless nickel

Nickel electroplating refers to the process of directional migration and accumulation of ions under the action of an electric field to form a coating. In addition to the main components such as the main salt, the plating solution also needs to add various electroplating additives and various auxiliaries, mainly to make the coating emit light and improve the overall performance. Flattening, refining crystals, avoiding pinholes, promoting cathodic polarization, etc. Nickel electroplating is in an electrolyte composed of nickel salts, conductive salts, pH buffers, and wetting agents, the anode is metal nickel, and the cathode is plated parts , Direct current is applied to deposit an average and dense nickel coating on the cathode. Bright nickel is obtained from the plating solution with brightener, and dark nickel is obtained from the electrolyte without brightener.

Electroless nickel plating is electroless nickel plating, also known as electroless nickel plating, which is the accumulation of nickel layer by the addition of reducing agent to provide catalytic power. The plating solution often needs to add main salt, stabilizer, reducing agent, complexing agent, buffer agent Etc. Electroless nickel plating has the technical characteristics of strong deep plating ability, good uniform plating ability, dense coating and low porosity, and its application range has been extended to various fields of industrial production.
