A Combustion Powder System uses a mix of oxygen and a combustion gas to create a flame outside of the spray gun of approximately 5500 F. The material that melts with this heat source is a powder.
The powder is fed into the center of the flame where it is melted. That is why it is called the Combustion Powder process. The powder is melted in the flame where the liquid metal is atomized. Atomization is created when a combination of the pressure from the flame; then it is injected around the flame.
The atomized molten metal now forms a columned stream. This is 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.
In addtion, this is also called the Powder Flame Spray Process.
Complete Spray System
The complete combustion powder system includes the combustion powder torch, gas flow meters, and air flow meters. In addition, an air trio regulator, airjet assembly, vibrator, transformer, gas regulators, and flash back arrestors are avialble. See each item below.
Gas Flow Meter
The PPS-2GF controls the oxygen and fuel for the WireJet series and the PowderJet series of guns. It is a direct replacement for the Metco 2GF. The standard system uses acetylene and oxygen, optional hardware is available to use propane, propylene, map, or natural gas.
The Air Trio uses a particle filter, water trap and air pressure regulator in one unit. There is an additional quick disconnect for cooling air jets or other auxiliary compressed air requirements.
High Spray Rate Applications
Use the PowderJet 86 for higher production applications. It is similar to the PowderJet 85 except it uses a powder feeder for significantly larger volumes of powder for larger production applications.
Use the PF-2800 powder feeder for larger powder use applicaitons.
Direct replacement parts for Metco 5PII and 6PII
