Plating and coating are two types of metal finishing that provide surfaces with new, more durable exteriors. But they each accomplish this goal in markedly different ways. To understand their differences and the benefits of each kind of metal finishing, learn about the important distinctions that separate plating and coating below.

What Is Plating?

During the plating process, a thin layer of metal covers a conductive surface. This is primarily done through electroplating, using an electrical current applied through a solution, in which a metal bar dissolves and coats the surface layer. Electroless plating can also achieve this same end, but through chemical means. Plating results in a product that possesses greater corrosion resistance, improved strength, and enhanced visual appeal. The majority of metals, from gold and silver to chrome and nickel, can be successfully plated. Automotive parts, jewelry, musical instruments, and electronic components are just a few commonly plated items.

What Is Coating?

Uncoated metal is susceptible to rust, corrosion, and damage. Applying a coating protects the integrity of the metal and reduces wear and tear on the product. What sets coatings apart from other types of metal finishing is the application process; a fine powder is spread evenly over the surface before being cured with heat. Epoxies, polyurethane, and other polymers are among the most frequently used coatings. On a very basic level, a coating is more like a sturdier form of paint that covers a product, while plating is a layer of metal covering a product. In addition to its protective benefits, coating creates a sleek, attractive finish. Cars, boats, airplanes, heavy machinery, and other items that are routinely exposed to the elements usually contain coated parts.
