Class Information
Number: 427/446
Name: Coating processes > Spray coating utilizing flame or plasma heat (e.g., flame spraying, etc.)
Description: Processes wherein (1) a gaseous flame is used to heat and project a coating material toward a substrate or (2) a coating material is converted to or engulfed by a highly ionized gas composed of ions, electrons and neutral particles in which the positive ions and negative electrons are roughly equal in number, and projected on to a substrate
