Which metal finishing step involves heating the coated metal to cure the finish?

• A. Baking
• B. Electroplating
• C. Dip coating
• D. Powder coating

Answer: (A)

Curing a coating with heat is the key idea here. After a finish is applied, many coatings—such as enamels or powders—need to be heated in an oven so the film chemically cross-links and hardens. That heating step is called baking, and it creates a durable, even surface by setting the coating. The other options describe ways of applying coatings or different processes, but they don’t specifically denote the heat-curing step.
