Plasma spray is a thermal coating process that produces a high-quality, strong, protective coating.
A wide range of plasma spraying technologies are used extensively in the coatings industry to deposit coatings onto structural materials, giving them protection against corrosion from high temperatures, wear, and tear.
The combination of high temperatures, high-energy heat sources, an inert spraying mechanism, and high-velocity particles, are the elements responsible for creating a high-strength and quality coating.
Plasma spray can be applied to a variety of surfaces, such as metal or ceramic, providing an exceptionally strengthened bond.
The Plasma Spray Process
A material such as argon is softened into molten form.
It is injected into a high-temperature plasma flame, usually in powdered form. It is heated rapidly and to a high velocity.
The molten material is then applied onto the substrate via a spray gun.
The spray gun consists of a water-cooled copper anode and a tungsten cathode. A gap between these components creates a rapid release, high-energy discharge that increases the temperature of the gas to 14,000 K high-temperature plasma.
On contact with the substrate, the plasma then cools rapidly to form a solid coating.
The process is then continued to build layers upon layers of particles, making for a densely packed, strong surface coating.
Plasma Spray Services
Plasma spray can be a costly and complex procedure to manage in-house. Specialist providers of plasma spray services can rise to any challenge or innovation on your behalf, making the process simple and straightforward to outsource.
