Plasma Spray Coatings
Plasma spray coatings offer the greatest variety of coatings due to the high temperature range of plasma spray guns. Our application engineers will ensure your component is coated using the optimum configuration.
With more than 200 thermal spray coatings available, our services are highly configurable to best meet your requirements. With outstanding technical support, delivery reliability and turnaround times, we will not only assist you in choosing the right coating for your requirements but also deliver a high quality service that meets your timescales.
If Plasma Spray isn’t the best solution, we also have HVOF, Flame Spray, Wire Arc, and Thermal Spray Aluminium services. Click on the following link to read more about our Thermal Spray Coating services.
How does the plasma spray process work?
The Plasma spray process is known as a ‘cold’ process as the substrate temperature can be kept low throughout (<150°C), and the coating thickness can be accurately controlled. The Plasma flame (argon, nitrogen, hydrogen and helium) melts the powder and propels the molten metal out of the spray gun and onto the substrate. The metal then cools and solidifies forming a very strong bond onto the substrate.
Plasma spray processes
- Ceramic coatings: e.g. Chrome Oxide, Aluminium Oxide, Zirconium Oxide
- Abradable coatings: e.g. Nickel Graphite, Nickel Aluminium or Nickel Chrome
- Pure Metals and Alloys: e.g. Aluminium, Copper Molybdenum, Nickel
- Carbides: e.g Tungsten Carbide, Chrome Carbide
