Abstract: A method for manufacturing and regenerating a functional surface of an anilox sleeve or anilox roller for a printing machine with a coating protecting against wear and corrosion. The anilox sleeve is preferably made out of a lightweight plastic on which an intermediate layer is applied and has a metal tube located above the intermediate layer. During a first phase, the worn engraving and the old layer are ground off from the cylindrical surface of the anilox sleeve, that is to say from the metal tube, and a coating, a carbidic tungsten carbide-cobalt-chromium layer (WC—Co—Cr) is subsequently applied. This carbidic layer is applied by a high-speed flame spraying (HVOF) process and subsequently functionalized by laser.

Abstract: A multi-layer protective coating for a substrate arranged in or on a vessel and method of forming multi-layer protective coating on a substrate arranged in or on a vessel. Multi-layer protective coating includes a thermal sprayed bonding layer formed on and in contact with a first face of the substrate prepared in a manner to allow the bonding layer to adhere, the bonding layer having a substrate face and a non-substrate face, a resistance layer made of a material resistant to impact forces and corrosion caused by a corrosive environment in a vicinity of the substrate arranged in or on the vessel, the resistance layer formed on and in contact with the non-substrate face of the bonding layer, the resistance layer having a bond face and a non-bond face, and a sealant layer formed on and in contact with the non-bond face of the resistance layer.

Abstract: Coatings on a substrate and application methods result in coatings that can withstand different types or groups of bulk cargo and operations. This novel approach includes use of a combination of layers of coating materials at certain thicknesses and applied with certain techniques. In certain embodiments, the coating system includes coatings applied to a pretreated substrate, e.g., blasted steel cargo hold plates of an oceangoing vessel. The coatings include a bond layer and a resistance layer, e.g., an anti-corrosive layer tailored to resist at least one of corrosion, erosion, impact and wear of the substrate.

Abstract: A process for producing a protective metal layer on tubes used in firing installations comprises thermal spraying on the tubes an atomized powder being formed from an alloy which comprises from about 15 to 35% Cr, from about 0.05 to 5.0% Mn, from about 0.01 to 3.0% C, from about 0.1 to 3.0% Si, from about 0.1 to 8.0% Mo, from about 2.0 to 15.0% Al, and balance Fe.

Abstract: A process for producing a corrosion-resistant protection on stabilizing wall surfaces and superheater tubes in sulfur-bearing hot gases which are used at surfaces temperatures of over 400.degree. C. in combustion installations, and a material in powder form which is suitable for that process, are intended to make it possible to use such wall surfaces and superheater tubes in sulfur-bearing hot gases in a good and durable fashion.For that purpose, to form a protective layer which is preferably from 0.2 to 1.5 mm in thickness, a metal powder which is sprayed out of a molten state, of a given composition, with a surface area of more than 200 cm.sup.2 /g, is applied with an autogenous flame spray torch, with a quantitative gas flow rate of between about 1000 to 3000 NL/h, or 1500 to 2500 NL/h, for the combustion gas. The preferred composition of the metal powder used in Cr 15% to 35%, Mn 0.05% to 3%, Mo 0.05% to 5.0%, C 0.1% to 3%, Si 0.1% to 3%, Al 2% to 15%, with the balance Fe.
