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 loose 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.
