DEFINITION

Classification: 427/460

Ionization or corona discharge utilized:

(under subclass 459) Processes wherein (1) the dissociation of an atom or molecule into electrons and ions, which facilitates the passage of current, or (2) the phenomena that occurs when an electric field is sufficiently strong to ionize the gas between electrodes and cause conduction, is used to assist in the deposition of the fluidized coating material.
