Plasma thermal sprays offer the greatest variety of coatings due to the high temperature range of plasma spray guns. 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.
Example Plasma sprays:
|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|
In addition to plasma thermal sprays, ACI Ltd offers a full range of over 200 thermal coatings.
