Electroplating vs. Galvanisation: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on December 3, 2023
Electroplating involves depositing a thin metal layer on an object using an electrical current, while galvanisation is coating iron or steel with zinc for corrosion protection.

Key Differences

Electroplating uses an electric current to reduce dissolved metal cations, enabling them to form a coherent metal coating on an electrode; while, galvanisation involves applying a protective zinc coating to steel or iron to prevent rusting.

Galvanisation typically refers to hot-dip galvanizing, a process where steel is submerged in molten zinc; however, electroplating often involves a more controlled and precise deposition of metal layers, used for both functional and decorative purposes.

In electroplating, the thickness and composition of the metal layer can be tightly controlled, making it ideal for electronic components; galvanisation offers a more rugged and long-lasting protection against environmental elements, especially for outdoor applications.

Electroplating is often used for small parts and electronics due to its precision and aesthetics, while galvanisation is more common in large-scale industrial applications like construction materials due to its durability.

Galvanisation provides a sacrificial layer, meaning the zinc corrodes instead of the underlying metal, while electroplating can use various metals (like gold, silver, or nickel) for specific properties, including corrosion resistance, solderability, or aesthetics.

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.
