Which term refers to a finish created when base metal is coated by another metal via an electrolytic process?

• A. Polished finish
• B. Plated finish
• C. Plastic
• D. Pouch

Answer: (B)

Plating is the finish created when a base metal is coated by another metal through an electrolytic process. In electroplating, the workpiece acts as the cathode and the coating metal as the anode (in a proper electrolyte), and electrical current drives metal ions from the solution to deposit a thin, uniform layer on the surface. The result is a plated finish, which can enhance appearance, corrosion resistance, and hardness. This differs from a polished finish, which is produced by mechanical smoothing rather than adding material, and from plastic or pouch, which involve non-metal materials or packaging rather than a metal coating. Common examples include nickel or chrome plating for a bright, durable surface.
