Metal finishing is a type of surface finishing that can be defined as the deposition of a metallic coating onto a product either to enhance performance, function or aesthetic qualities while providing overall added value. While it's not obvious on a daily basis, many objects have been subjected to metal finishing for use in our normal lives. These include parts in a car, aircraft, fencing, medical and dental devices, industrial machinery or even beautiful pieces of art. The term finishing is based on the fact that it's normally the last step of the manufacturing process (save for any heat treatment).
