Trivia: "What is the difference between plating and painting?"
The materials and construction methods for plating and painting are completely different. Here is a simple explanation of the differences between plating, including hard chrome plating, and painting.
○ Plating This is a technique that forms a thin metal film on the surface of a material to prevent rust, improve appearance, or impart functionality. Plating can be broadly divided into wet plating and dry plating, with hard chrome plating classified as wet plating. Wet plating involves forming a film in a solution of dissolved metal and is further classified into electroplating, which uses a power source, and electroless plating, which does not. Dry plating, on the other hand, forms a film in a vacuum or similar environment and is called dry plating because it does not involve immersion in a solution. Dry plating is further divided into physical vapor deposition (PVD) and chemical vapor deposition (CVD). ○ Painting, Coating This is a technique that forms a coating film by applying or spraying paint onto the surface of a material, with similar purposes as plating, such as preventing rust, improving appearance, and imparting functionality. Painting methods range from simple manual application using brushes to high-pressure spraying of paint, methods that heat and cure the paint, powder coating where powdered paint is electrostatically adhered and then heated to melt, and electrodeposition painting, where electricity is passed through a solution of dissolved paint to form a coating film.
