Abstract
A method for protecting a substrate from corrosion, which method comprises in sequence: a first step including plasma polymerization of a precursor monomer and deposition of the resultant polymer onto at least one surface of a substrate; a second step including exposing the polymer to an inert gas in the presence of a plasma without further deposition of polymer onto the or each surface of the substrate; a third step including plasma polymerization of the precursor monomer used in the first step and deposition of the resultant polymer onto the polymer deposited in the first step so as to increase the thickness of the polymer; and optionally, a fourth step including exposing the polymer to an inert gas in the presence of a plasma without further deposition of polymer onto the or each surface of the substrate.
