Plating and deplating are two opposite processes that involve the transfer of metal ions between a solution and a substrate. The main difference between plating and deplating is the direction of the transfer.
Plating refers to the process of depositing metal ions onto a substrate to form a thin, even layer of metal. This process is also known as electrodeposition, and it is commonly used to improve the appearance, wear resistance, and corrosion resistance of metal parts. Plating is achieved by passing an electric current through a solution that contains dissolved metal ions, and placing the substrate to be plated (e.g., a metal part) in the solution as the cathode (negative electrode). As a result of the electric current, the metal ions in the solution are attracted to the cathode and are reduced to form a solid metal layer on the surface of the substrate. The metal layer adheres to the substrate through a combination of electrostatic forces and chemical bonding, resulting in a durable and uniform coating.
Deplating refers to the process of removing metal ions from a substrate and dissolving them into a solution. This process is also known as corrosion or dissolution, and it is the result of chemical reactions that occur when metal parts are exposed to corrosive environments, such as seawater. Deplating can occur in two ways: through chemical reactions that directly dissolve metal ions from the substrate (e.g., metal ionization), or through electrochemical reactions that involve the transfer of electrons between the substrate and the surrounding environment (e.g., electrolysis). In either case, the metal ions that are dissolved into the solution can be carried away by the fluid flow and cause further corrosion or damage to other metal parts that they come into contact with.
In summary, plating involves the deposition of metal ions onto a substrate to form a protective layer, while deplating involves the removal of metal ions from a substrate and dissolution into a solution, which can lead to corrosion and damage of metal parts.
