Abstract (en)
[origin: WO2021089102A1] The invention relates to a method for coating a component, wherein the method comprises the following steps: - providing a gas phase, which contains at least one tetra-alkoxy silane as first silicon-containing precursor, at least one functionalised silicic acid ester with a phenyl, vinyl, allyl, thiol, amino, acryloxy, epoxy, nitrile, isocyanate, isothiocyanate or methacrylate group as second silicon-containing precursor, at least one catalyst, water and inert gas, optionally hydrogen, or consists of these substances, the silicon-containing precursors being added in metered fashion to the gas phase separately from one another and separately from the water and the catalyst, - chemically reacting the first silicon-containing precursor with water in the gas phase so as to form first reaction products, - chemically reacting the second silicon-containing precursor with water in the gas phase so as to form second reaction products, - depositing the reaction products on the component, the reaction products of all precursors together forming a coating on the component based on amorphous silicon dioxide.
