Thermal Spray: Plasma Spray
For those who are unfamiliar with plasma spray, the process involves injecting a powder into a high temperature plasma flame where it is heated and accelerated onto the surface of a component. The process provides high particle velocities leading to relatively dense, low porosity coatings.
A variety of materials including metals, ceramics, cermets and plastics can be applied with the benefit of restricting bulk component temperatures below 150°C in most cases.
Although extensively used in the Aerospace sector, the process is also widely used in the Oil, Gas, Biomedical, Textile, Printing, Automotive and Construction industries.
The process provides component surface enhancement for wear resistance in fretting, abrasive and sliding applications, corrosion resistance, thermal insulation or a combination of these, both under ambient and high temperature conditions.
