Chemical Conversion Coating
(Clear Chromate & Yellow/Gold Chromate)

Chemical conversion coating is a process of depositing an oxide layer over a metal surface to improve its durability, surface finish, and corrosion resistance.

One type of chemical conversion coating is chromate, which enables the metal to react with the oxide layer and form a passivated metal chromate on the surface.

Clear chromate and yellow/gold chromate are two variations of this process.

Chromate is commonly used to protect metals such as aluminum and zinc alloys from material degradation by reducing their reactivity. This cost-effective corrosion inhibitor also serves as a primer for painting, provides a decorative finish, and improves electrical conductivity.

Understanding the benefits of chromate is crucial, as it helps maintain the integrity of vital components and prolongs the lifespan of metal parts.
