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.

Method for obtaining a floor covering and product obtained

To increase the anti-wettability of a body vis a vis a fluid the body is subjected in a treatment enclosure to a post-discharge nitrogen plasma. A fluorinated vapor is fed into the plasma on the input side or on the output side of the discharge cavity.

Method for increasing the anti-wettability of a body

A method for increasing homogeneously the wettability of a porous body vis a vis a fluid includes a step in which the porous body is exposed in a treatment chamber to a nitrogen plasma generated by an electromagnetic wave discharge in nitrogen gas. Applications include increasing the wettability of a marker tip.

The present invention relates to a method of treating a packaging element, specially a sealing element, comprising the coating with a polymer film of at least those parts of said element which are liable to be in contact with the products packaged, wherein said coating is produced by polymerization, assisted by cold-far-remote-plasma, of at least one monomer chosen from siloxanes and silazanes of formula: ##STR1## in which: A represents an oxygen atom or the NH group and;

A workpiece having a surface to be metallised is placed in an enclosure. A plasma is produced in a plasma tube which extends into the enclosure, the plasma having a post-discharge zone in which the surface to be metallised is placed. Vapour of a metal carbonyl compound is injected into the enclosure, such compound dissociating in the post-discharge plasma to cause the metal to be deposited on the surface.
