  • Patent number: 11319631
    Abstract: A steel substrate coated on at least one of its faces with a metallic coating based on zinc or its alloys wherein the metallic coating is itself coated with a zincsulphate-based layer—includes at least one of the compounds selected from among zincsulphate monohydrate, zincsulphate tetrahydrate and zincsulphate heptahydrate, wherein the zincsulphate-based layer has neither zinc hydroxysulphate nor free water molecules nor free hydroxyl groups, the surface density of sulphur in the zincsulphate-based layer being greater than or equal to 0.5 mg/m2. A corresponding treatment method is provided.
    Type: Grant

  • Patent number: 9249512
    Abstract: The present invention relates to a process for coating a surface of a substrate made of nonmetallic material with a metal layer consisting of providing a substrate made of nonmetallic material; subjecting a surface of said substrate to a treatment for increasing the specific surface area thereof; subjecting the resulting surface to an oxidizing treatment; contacting the resulting substrate with a solution containing an ion of a metal from groups IB and VIII of the Periodic Table; obtaining a substrate comprising ions of a metal that are chemically attached to the nonmetallic material constituting the substrate on at least one of its surfaces; subjecting the ions to a reducing treatment to obtain a substrate comprising atoms of a metal that are chemically attached to the nonmetallic material constituting the substrate on a part of at least one of its surfaces; and contacting the resulting surface with a solution containing ions of a metal.
