Coating method where a powder using supersonic gas jet is thrown against the workpiece and is attached by plastic deformation. Beskrivning The process The surface coating powder [1] supplied through the center of the spray gun and thrown onto the workpiece by means of a gas [2], usually helium, which has been heated and accelerated in an antechamber. [3] The process is so fast that the powder does not have time to melt before adhering to the surface by plastic deformation and a coating is built up in such a way on the surface.
