Combustion Powder

Available from Thermal Spray Depot

A combustion powder system uses a combustible gas mixed with oxygen to create a flame outside of the spray gun of approximately 55000 F. This is the heat source to melt the material to be sprayed. The material to be sprayed is in the form of a powder that is fed into the center of the flame where it is melted. Once it is melted in the flame, the liquid metal is atomized from a combination of the pressure from the flame and compressed air that is injected around the flame. The atomized molten metal now forms a columned stream, similar in appearance to a spray paint pattern, except this is molten metal. The molten stream of metal is deposited on the component to be coated at a thickness of .0005" (.0127mm) per pass to .003" (.0762 mm) per pass. The variation of thickness per pass is depended on the material being sprayed and the amount of heat build up on the part being coated.

The complete system includes the combustion powder gun complete in a metal case, gas flow meters, air flow meters, air trio, airjet assembly, vibrator, transformer, gas regulators, and flash back arrestors. When you purchase the complete system from us we include a set of free hoses.
