Plating (English electroplating) is the use of electrolysis principle to plate a thin layer of other metals or alloys on the surface of certain metals. It is the use of electrolysis to attach metal films to the surface of metal or other materials. Prevent corrosion, improve wear resistance, conductivity, reflective properties and enhance aesthetics, such as metal button plating.
Electroplating principle:
In the plating bath containing the plating solution, the cleaned and specially pre-treated pieces to be plated are used as cathodes, and the anodes are made of plated metal, and the two poles are respectively connected to the negative electrode and the positive electrode of the DC power source. The plating solution consists of an aqueous solution containing a metal-coated compound, a conductive salt, a buffer, a ph regulator, additives, and the like. After the power is applied, the metal ions in the plating solution move to the cathode under the action of a potential difference to form a plating layer. The metal of the anode forms metal ions into the plating solution to maintain the concentration of the metal ions being plated. In some cases, such as chrome plating, insoluble anodes made of lead and lead-antimony alloys are used, which only serve to transmit electrons and conduct current. The chromium ion concentration in the electrolyte needs to be maintained by periodically adding a chromium compound to the bath. When electroplating, the quality of the anode material, the composition of the plating solution, the temperature, the current density, the electrification time, the stirring intensity, the precipitated impurities, the power waveform, etc. all affect the quality of the plating and need to be controlled in a timely manner.
