Electroplating vs. Anodizing: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on December 18, 2023
Electroplating adds a metal layer using electric current, while anodizing thickens a metal's oxide layer using an electrolytic process.

Key Differences

Electroplating involves depositing a metal layer on an object via an electrical current, which attracts metal ions to the surface. Anodizing, in contrast, uses an electrochemical process to form a protective or decorative oxide layer on a metal surface.

The primary purpose of electroplating is to improve corrosion resistance, enhance appearance, or increase thickness. Anodizing also aims to enhance corrosion resistance, but it uniquely alters the surface structure of metals like aluminum for better wear resistance.

In electroplating, various metals like gold, silver, or nickel can be used for coating. Anodizing is mostly limited to specific metals like aluminum, where the oxide layer is integral to the metal itself.

Electroplating

The art or process of depositing a coating (commonly) of silver, gold, or nickel on an inferior metal, by means of an electric current. The metal to be deposited on an article is usually used as the anode and the article to be plated as the cathode, in an electrolyte solution in which the plating metal is the cation. The process is conducted in a tank called an electroplating bath, which holds the electrolyte solution.
