  • Patent number: 11845105
    Abstract: A method for depositing a coating on a substrate is disclosed. A first precursor comprising fluoro-acrylate monomers, fluoro-alkyl acrylate monomers, fluoro-methacrylate monomers, fluoro-alkyl methacrylate monomers, fluoro-silane monomers, or a combination or derivates thereof is provided. A second precursor comprising linear siloxanes, silane monomers, cyclosiloxanes, cyclosilane monomers, or a combination or derivates thereof is provided. The first and second precursors are co-injected in a treatment region. An atmospheric or reduced pressure plasma discharge is created in said treatment region. The substrate coating comprises alternated multi-stacked nanostructures and is formed by copolymerization of the first and second precursors.

  • Patent number: 11767594
    Abstract: A method for plasma coating an object includes an object profile, having the steps of: a) manufacturing a replaceable shield comprising a jet inlet, a nozzle outlet and a sidewall extending from the jet inlet to the nozzle outlet, wherein the nozzle outlet includes an edge essentially congruent to at least part of the object profile; b) detachably attaching the replaceable shield to a jet outlet of a plasma jet generator; c) placing the object at the nozzle outlet such that the object profile fits closely to the nozzle outlet edge; d) plasma coating the object with a low-temperature, oxygen-free plasma at an operating pressure which is higher than the atmospheric pressure by providing a plasma jet in the shield via the plasma jet generator and injecting coating precursors in the plasma jet in the shield.

  • Publication number: 20150132590
    Abstract: The present invention is related to a method for protecting a metal substrate against corrosion comprising the step of: —generating a plasma in a gaseous medium by means of a plasma device; —placing the substrate in contact with the plasma, or in a post-plasma area of said plasma; —introducing in said plasma or in said post-plasma area a corrosion inhibitor along with an organic precursor, thereby depositing a barrier layer comprising the corrosion inhibitor, the deposited layer protecting the metal substrate against corrosion.
