Chromate Conversion Coating and its Applications in Building

by | Apr 22, 2022 | Metal

Chromate Conversion Coatings are a type of coating that protect metal surfaces from corrosion. They work by stopping the flow or adhering to dirt. This causes it to turn brown and then black due to its ability absorbs oxygen molecules through hydroxyl groups (the parent compound). This process can be sped up with exposure. This article is based on the applications of this coating method.

Prevent Chloride Corrosion

Chromate conversion coatings are a great way to protect metal against corrosion from chlorides. The first use protects the exterior of bridges, ships, and other large structures from environmental factors. The factors include water and air pollution that can cause damage. The damage is mainly due to bad weather conditions, which make it difficult to access some parts.

Increase the Resistance of Surfaces

They also beneficial in increasing reflectivity and improving resistance against wear and tear. This makes them an attractive option for many surfaces that need extra protection or enhancement, like bridges in high-traffic areas. These surfaces experience lots of pressure daily due to their location near major roads with lots passing through per hour.

Prevent Rusting

The coating creates a barrier that prevents oxygen and water access to the metal. These two factors would cause detractive rusting action on the metal.

Decoration

Chromate conversion coating is used in many different applications. It can be applied to paper and fabric, which increases their resistance to inking. Color coatings also protect the underlying surface by shifting color from one part of an object onto other parts that are not being decorated.
