When working with our technical staff on corrosion prevention solutions, it is very important to understand the environment in which the component is exposed. Our materials engineers use that information to create a corrosion protective coating solution specific to that components requirements. Our expertise in understanding materials properties and various coating processes will be used to select the best deposition methodology and optimum process parameters.


Galvanic Corrosion Prevention Coatings

Galvanic corrosion resistant coatings are made from materials such as iron and steel alloys. These coatings are considered sacrificial coatings as they will preferentially slowly corrode while minimizing the corrosion occurring to the steel. This technology has been used on many components including very large ones such as bridges found in coastal areas and wind energy windmills. The technology has been proven to be far more effective than paints for providing longer term protection.

Corrosion Resistant Coatings

There are several corrosion resistant coatings that can be engineered to provide a corrosion resistant barrier for many substrate materials in many corrosive environments. Nickel-chromium and cobalt-chromium alloys produce very good corrosion resistant coatings. These materials can be deposited with very low porosity levels (less than 1%) to prevent corrosive attack through porous connections. Oxide ceramics are also very corrosion resistant materials and can be applied to most metal substrates to provide corrosion resistant coatings.


Wear & Corrosion Resistant Coatings

Corrosion and wear are combined in many applications. Fortunately several different materials can be engineered to provide both wear and corrosion resistance coatings. Cermet materials, (ceramic and metal) such as carbides with corrosion resistant metal binders are examples of coatings that provide protection to both corrosion and wear, Oxide ceramics are very hard and corrosion resistant which also make them good candidates as coating solutions for these applications.
