They all refer to a surface coating solution involving the projection of small molten particles on to a pre-prepared substrate.

Processes

Flame spraying is one of the oldest methods of spraying. A chemical reaction takes places between a combustible fuel and oxygen. This is then transferred to a heat gun machine via a wire. Compressed air is forced through the nozzle, allowing the particles to be sprayed on to the substrate.

Arc spraying involves the melting of wires with electricity. These molten particles are then atomized, leaving sprayable droplets which are formed into a spray steam. This can then be applied to a pre-prepared surface.

Plasma spraying involves a plasma gun. An electrically charged arc forms between the nozzle and the electrode. This allows for a plasma jet and powdered particles to be accelerated through the nozzle, resulting in a high-adherence surface coating upon impact.

Thermal Plasma Spray Specialists

Spraying processes are used in a variety of industries and processes. The purpose of this type of spraying includes increasing the durability and lifespan of a component. The coating allows resistance against extreme temperatures, corrosion, friction, moisture or gradual wear, all whilst maintaining their integrity.

Thermal plasma spray specialists such as https://www.poeton.co.uk/surface-treatments/thermal-metal-sprays/plasma-coatings offer a variety of plasma spray processes, including an expertly formulated and unique ceramic-metallic blend coating.
