Thermal Spray

Thick-Film: Thermally Applied Coating Services

The processes that are used to create these coatings are often referred to as metallizing, plasma spraying, metal spraying, arc spraying, ceramic coating and a few other, less popular, names. Each of these applies a subset of the entire process of applying a coating of metal, oxide, ceramic, carbide or composite material to a substrate using heat.

A material with a liquid phase is prepared in either wire or powder form. This material is delivered to a heat source, where it melts and is atomized into a spray that is projected towards the prepared substrate. When the individual particles strike the intended surface they lose their heat to the substrate and solidify building up a coating.

The purpose of the coating is always the same; surface modification. Such modification may simply be to restore dimensions to a worn part, to improve wear resistance, to provide corrosion or heat oxidation resistance, electrical conductivity or resistivity, thermal insulation or any other desirable characteristics that the parent material does not possess.

The specific characteristics of a coating vary with the source material and the process used to apply it.  Metal Fusion, has extensive experience in the restoration of turbine engine parts, mechanical components and computer chip fabrication components such as shields, masks, and in some cases, targets. We have successfully produced coatings for a broad range of industries including the biomedical device industry and architectural components where cosmetics are the primary objective. The variety of applications is virtually without limit.

If you think that this may be an approach that could improve or salvage your parts, give us a call and we will investigate your intended application to verify that this process will serve your needs.
