Abstract
A method for obtaining a floor covering comprising one or more resilient polymer substrates coated with a protective layer is described, wherein said layer contains one or more amorphous inorganic components and has a Vickers hardness of more than 1 GPa and a modulus of elasticity (Young's modulus) of less than 80 GPa, using a delayed cold plasma that induces a decomposition reaction of a volatile precursor compound so that a thin film of said amorphous inorganic component is formed on said substrate. A floor covering comprising one or more resilient polymer substrates obtained by the method of the invention is also described, wherein the substrate is coated with a protective layer containing one or more amorphous inorganic components and with a Vickers harness of more than 1 GPa and a modulus of elasticity (Young's modulus) of less than 80 GPa.
