Thermal Spraying Process



FLAMESPRAY
In the Flamespray process, the raw material in the form of a single wire, cord or powder, is melted in an oxygen - fuel gas flame. This molten material is atomised by a cone of compressed air and propelled towards the workpiece.




ARCSPRAY
In the Arcspray process, the raw materia], in the form of a pair of metallic wires is melted by means of an electric arc. The molten material is atomised by compressed air and propelled towards the workpiece.




PLASMASPRAY
Plasma is the term for gas which has been raised to such a high temperature that it ionises and becomes electrically conductive. When Plasma spraying, the plasma is created by an electric arc within the nozzle of the gun. The gas is formed into a plasma jet as it emerges from the gun nozzle. Powder particles are injected into this jet where they melt and then strike the surface at high velocity.




HVOF
Liquid fuel and oxygen are fed via a pre-mixing system into a high pressure combustion chamber where a stream of high pressure gas is produced. Expansion of the gas velocity to approximately 1500 m/sec prior to injecting the powder ensures the powder particles impact the substrate with tremendous energy.
