The Boeing Company has obtained a patent for a method for applying a silicon oxy-carbide coating onto a substrate comprised of the steps of introducing a shielding gas and a plasma-source gas to an atmospheric plasma device to generate an atmospheric plasma; introducing a cyclic organosiloxane precursor to the atmospheric plasma, the cyclic organosiloxane precursor being carried by a carrier gas; and while the cyclic organosiloxane precursor is being introduced to the atmospheric plasma, positioning the substrate relative to the atmospheric plasma device such that the atmospheric plasma deposits the silicon oxy-carbide coating onto the substrate.
