In this process the spray material is fed in powder form through the gun using a transport gas injecting it centrally into a burning gas/oxygen mixture, where it is melted and delivered onto the substrate.

Because nickel-based and cobalt-based meltable alloys and ceramic materials cannot be produced in wire form powder spraying was developed in 1956. Over the years powder spraying has been enhanced to include many other types of spraying powders. The way the powder spraying system works is similar to that of a wire spraying system.
