TURBOCAM International
Plasma Spray Coating

TURBOCAM International broadens its engineering and manufacturing solutions to offer plasma coating, a type of thermal spray application. The plasma coating provides wear protection to our aerospace products.

Robot for plasma spray coatingThermal spray techniques are processes where melted materials are sprayed onto a surface. In the plasma spray process, a powder melts within a plasma jet creating a plasma plume. The plasma jet is an ionized region of gas formed by passing argon through a high voltage electric arc inside the plasma torch. Introducing a secondary gas, such as hydrogen, increases the heat transfer properties of the plasma plume. Temperatures can reach 5,000° C in the plasma plume, where the feedstock material melts while being propelled towards the substrate. The molten droplets flatten and rapidly solidify forming a deposit, which remains adhered to the surface in the form of a coating.

The large number of technological parameters influencing the interaction between the powder particles and the plasma jet directly affects the coating properties. Such parameters include feedstock type, gas composition and flow rate, energy input, standoff distance, and substrate cooling time. A certified metallographer performs the evaluation of these properties in the TURBOCAM Energy Solutions metallography lab.
