Corona Plasma is a variation of atmospheric plasma generation that is produced by blowing air through a series of high voltage arcs causing the air to ionize.  This ionized air can be used to provide an increase in surface energy in non-conductive surfaces.  The advantages of these types of plasma sources to produce surface treatment is low cost and the use of room air as a feed stock.  The disadvantages of these plasma sources is they do not work on conductive materials, the plasma is lower in density to other sources and the high voltage arc can be an ignition source.  The low cost and moderate shift in surface energy provided by a corona plasma technology can make it an option for consideration in some manufacturing solutions.
