In plasma spray process the heat source (plasma) is formed by the generation of a high-density arc current in the space between a cathode and an anode filled with a monatomic gas such as argon and a diatomic gas such as hydrogen. The ionized gases heat up to temperatures approaching 15,000°C and expand to reach supersonic gas exit velocities.
Properties of the plasma stream can be controlled by cathode-nozzle configuration, gas type, gas flow, gas mixture ratio and electric arc power levels. The resulting plasma stream can therefore greatly influence the degree of melting and acceleration of the chosen material, allowing deposition of coatings with tailored microstructural properties for specific industrial applications.
