Abstract: A method of making a gas-impermeable, chemically inert container wall structure comprising the steps of providing a base layer of an organic polymeric material; conducting a pair of reactive gases to the surface of the base layer preferably by pulsed gas injection; heating the gases preferably by microwave energy pulses sufficiently to create a plasma which causes chemical reaction of the gases to form an inorganic vapor compound which becomes deposited on the surface, and continuing the conducting and heating until the compound vapor deposit on the surface forms a gas-impermeable, chemically inert barrier layer of the desired thickness on the surface. Various wall structures and apparatus for making them are also disclosed.

Abstract: Transparent, refractory coatings and methods for their application to environmentally exposed substrates are disclosed. The coatings can be deposited over organic decorative materials, which generally prevent application of hard, protective, inorganic materials due to emission of exudates and vulnerability to excessive heat. The coatings are applied using plasma-enhanced chemical-vapor deposition techniques that reduce reaction temperatures and produce multilayer structures that seal organic exudates before a final layer of coating is applied, such multilayer protective coating structures being particularly suitable for protecting automobile bodies and the like against degrading external forces.
