What Are Metal Coatings?
Metal coatings are applied to metal surfaces to protect them from corrosion, wear, and other environmental factors. They also enhance the metal’s appearance and, in some cases, improve its performance characteristics. Coatings can be applied through various methods, including electroplating, thermal spraying, and chemical treatments.
