Abstract
Abstract An electric deposition process providing a glow discharge by virtue of electrical energy fields provided internal to a deposition chamber enables with one step to provide a protective coating of a surface of a substrate material by repolymerizing a polymer solid starting material. A carrier gas such as argon, xenon or krypton is used in the deposition chamber for the energy field to act upon it, provide the glow and cause the glowing gas to volatilize particles of the starting material and be deposited as the protective coating on the substrate.
