An introduction to plasma spraying

Thermal plasma spray is an industrial process used to apply a protective coating to a substrate to enhance its resistance to wear and corrosion.

How does plasma spray work?

The plasma spray process uses an ionised gas called plasma to create a high-velocity flame, which is used to melt a powdered coating material. This material is then projected onto the substrate, where it cools very quickly, forming a dense, strong protective layer.

Applications and costs of thermal plasma spray

Because of the risks and complexity involved in the plasma spray process, it must be conducted by specially trained experts, such as https://www.poeton.co.uk/surface-treatments/thermal-metal-sprays/plasma-coatings/. This means it is not a cheap option, but it does deliver outstanding and consistent results across a wide range of different materials and use cases.

What materials can be treated with thermal plasma spray?

Thermal plasma spray is a very versatile process that can be used to treat a range of substrate materials that include metals, ceramics and composites. It is a very effective method of applying a protective coating to irregularly-shaped objects and to those intended for use in very challenging environments such as marine, aerospace, and automotive.

Why choose thermal plasma spray?

Although there are many methods by which a protective coating can be applied to a substrate, the thing that sets thermal plasma spray apart is its exceptional long-term durability. The coatings applied with this method outperform any other coating method in terms of density and corrosion resistance, making it the obvious solution for substrates intended for use in demanding environments.
