What is Thermal Plasma Spray?

Thermal plasma spraying is used across many industries, such as aerospace, automotive, mechanical and marine. Its purpose is to provide a protective coating on applications such as buildings, aeroplanes, or other structures, particularly those that are exposed to extreme conditions because of temperature, environment, chemicals, or humidity.

The Advantages of Thermal Plasma Spray

The process of plasma spraying allows various materials to be coated in a high-quality, dense material. So strong is the coating that it is capable of meeting aerospace requirements. Materials used for coating may include ceramics, metallics, cermets, alloys, plastics, or composites.

Coating materials are sprayed using the pressure of a high-heat gas. Once the material is bonded to the surface, it affords the material with properties such as protection against corrosion and extreme heat, lubricity, and electrical or thermal conductivity.

The Thermal Plasma Spray Process

The coating starts off in powdered form. Once it has been heated so that it becomes molten, a plasma torch is used to spray the coating onto the substrate surface.

Within the nozzle of the plasma torch is an electrical arc, which allows plasma – an extremely high-temperature gas – to form. The powdered particles are injected into the plasma stream, where they are then sprayed onto the substrate surface at high velocity.

Plasma Spray Specialists

The plasma spraying process is often controlled and carried out using cutting-edge technology and with the assistance of state-of-the-art robotic manipulation. It is possible to achieve a high-quality coating in a variety of thicknesses via advanced processing techniques.
