What is bimetallic coating?

Apr 16,2024

A bimetallic coating is a type of surface treatment where two different metals are deposited onto a substrate, typically through a process like electroplating or thermal spraying. The purpose of applying a bimetallic coating is usually to impart specific properties to the substrate that neither metal alone could provide.

For example, one metal might offer corrosion resistance, while the other provides hardness or wear resistance. By combining these metals in a coating, the substrate can benefit from the synergistic effects of both materials, enhancing its overall performance and durability.

Bimetallic coatings are commonly used in industries such as automotive, aerospace, and manufacturing, where components are subjected to harsh environments or wear conditions. They can help extend the lifespan of parts, improve efficiency, and reduce maintenance costs.
