Method for the deposition of coatings upon substrates utilizing a high pressure, non-local thermal equilibrium arc plasma

摘要

A method is provided for the deposition of coatings upon substrates utilizing a high pressure, non-local thermal equilibrium arc plasma including the steps of generating a non-LTE arc plasma at a pressure greater than about 0.1 atmospheres, introducing a coating material into the arc plasma, positioning a substrate material proximate to the arc plasma whereby activated species of said coating material formed by the arc plasma contact the substrate to form a coating.
