ABSTRACT:
The electrogasdynamic coating system includes an electrogasdynamic gun for charging material particles indirectly. The gun has a gas inlet which receives from a gas source a pressurized gas in which an condensable vapor is entrained. Corona and attractor electrodes are disposed in communication with the gas inlet for ionizing the ionizable vapor. A dielectric tube extends from the electrodes downstream to a mixing chamber. A first fluid material inlet is connected with a first source of powder or liquid material and a second fluid material inlet is connected with a second source of powder or liquid material. The first and second fluid material inlets are connected with the mixing chamber such that particles of the first and second fluid materials are mixed with the gas and vapor. The vapor condenses and coats the particles during mixing causing them to become charged. In use, a condensable vapor is entrained into a gas flow, the gas flow is passed across corona and attractor electrodes to ionize the vapor. The ionized vapor condenses and is mixed with first and second fluid material particles such that the particles become charged. In this manner, the particles become charged without coming in contact with the corona or attractor electrode.
