Electroplating is a process of plating a layer of metal or alloy on the surface of a metal or other material using the principle of electrolysis. In an electroplating bath, the plated material serves as the cathode, and metal ions in the electrolyte move toward the cathode under the force of an electric field and form a metal coating by reductive deposition on the cathode surface.

Electroplating is a process of plating a layer of metal or alloy on the surface of a metal or other material using the principle of electrolysis. In an electroplating bath, the plated material serves as the cathode, and metal ions in the electrolyte move toward the cathode under the force of an electric field and form a metal coating by reductive deposition on the cathode surface. This method not only protects the substrate, but also improves its aesthetics and functionality.
Specific steps of electroplating
Preparation stage: Ensure that the work area is clean and ready for the required equipment such as plating tanks, power supply, etc.
Pre-treatment: Clean the surface of the plated object, remove oil, oxide film and other impurities to ensure that the surface is clean and free of pollution.
Plating: Put the plated object as cathode into the plating tank, adjust the current and voltage, so that the metal ions in the electrolyte are reduced and deposited on the surface of the cathode to form the plating layer.
Post-treatment: After plating is completed, the plated object is cleaned to remove residual electrolyte and other impurities.
Application and importance of electroplating
Electroplating technology is widely used in the electronic industry, communications, military industry, aerospace and other fields, used to improve the wear resistance, electrical conductivity, reflectivity and corrosion resistance of materials. In addition, electroplating can be used for decoration and protection to make products more beautiful and durable.
