What term describes a finish created by coating a base metal with another metal through an electrolytic process?

The term that describes a finish created by coating a base metal with another metal through an electrolytic process is indeed "plated finish." This process, known as electroplating, involves using electrical currents to deposit a layer of metal onto the surface of another metal. This technique is often used to enhance the appearance of the base metal, provide corrosion resistance, and increase durability.

Electroplating is widely used across various industries for functions like decorative finishes in jewelry or automotive parts, as well as functional improvements in electronic components. The high adherence and uniformity achieved through the electrolytic process make plated finishes both aesthetically appealing and protective.

Other terms such as galvanized, brushed, and coated finishes refer to different processes and characteristics. A galvanized finish involves a specific process where zinc is applied to prevent rust, a brushed finish pertains to a textured surface treatment, and a coated finish can refer to a variety of applications that do not necessarily involve metal deposition through electrolysis. Thus, "plated finish" is the precise term for the described process.
