Coating material in powder form is fed into a heat source created by ionization of a gas in an electric arc between two electrodes. The substrate and coating material is locally melted ......

In powder flame spraying, the spraying consumables in powder form are melted in an acetylene-oxygen flame and are accelerated on to the prepared surface by means of expanding combustion.

When arc spraying two spraying wires of the same or different kindly are melted in arc and are sprayed with atomizing gas i.e

In the HVOF-spraying process a continuous gas combustion with high pressure is carried out in the combustion chamber.In the central axis spraying consumables in powder form are fed into.
