Definitions

  • the invention relates to a coated body, in particular roller, carbon fiber reinforced plastic (CFRP) for paper and printing machines, with a primer layer and applied to the primer layer, wear-protective layer of hard metal or oxide ceramic and a method for producing such a body.
  • CFRP carbon fiber reinforced plastic
  • CFRP roller bodies are enjoying increasing popularity in paper machines and printing machines due to their low weight and at the same time extreme flexural rigidity.
  • the disadvantage is only the need for a coating, generally against wear or other stresses that drives the price in the current state of the art in the air.
  • coatings ceramic and hard metal coatings have prevailed, which are mainly produced by thermal spraying, namely plasma and flame spraying.
  • Elaborate and thus price increasing are less these known coating methods as the hitherto customary primer preparation, eg in DE 41 16 641 A1 or in EP 0 514 640 B1 such as EP 1 129 787 A and DE 101 27 908 A is described.
  • the CFRP roller is covered with another layer of synthetic resin into which previously large volumes of a typical adhesion promoter, for example NiAl or NiCr powder, have been dispersed.
  • a typical adhesion promoter for example NiAl or NiCr powder
  • a first grinding takes place, so that the dispersed-in adhesive promoter particles are ground.
  • ground primer particles are, so to speak, the adhesion points for further treatment by thermal spraying by means of NiCr or NiAl adhesion promoters and subsequent application of the functional layer of ceramic or hard metal.
  • Such coatings are only possible if the thermal load of the CFRP roller body is kept correspondingly low by adequate cooling measures, so that no delamination of the carbon fibers in the synthetic resin matrix occurs or the latter is damaged.
  • Out DE 93 05 806 U1 is a gravure roll with a sleeve of thermally wound fiber-reinforced thermoplastics known, wherein the fiber reinforcement may consist inter alia of carbon fibers.
  • a layer of copper or a copper alloy by thermal spraying, in particular plasma spraying or high-speed flame spraying, applied directly. In the copper layer, the necessary for the gravure printing engraving is introduced.
  • DE 100 37 212 A1 describes a particular for sports equipment, for example in the field of a golf club head, certain, at least partially thermally coated, fiber-reinforced plastic.
  • a primer layer of zinc, zinc alloys, aluminum alloys and / or exothermic acting materials during the injection process such as nickel-aluminum or molybdenum is applied to a carbon fiber-reinforced plastic base body for example by means of a thermal spraying process.
  • Thermal spray on the primer layer is a wear protection layer of metals, metal alloys, Oxides, carbides, borides, plastics or mixtures of said substances applied.
  • JP 02 270 954 A describes a method in which a CFRP cylinder intended for paper machines is preheated and provided by plasma spraying with a molybdenum base layer, and in which a ceramic protective layer is applied by flame spraying onto the molybdenum base layer thus produced.
  • Out GB 887,366 is a method of multilayer coating of plastics with metals or alloys by flame spraying, in which the first deposited layer has a thermal expansion coefficient which is greater than that of the plastic, while the subsequent layer or layers has a coefficient of thermal expansion (smaller than) which is the plastic.
  • Body in particular rolls of CFK in EP 0514640 B1 or in DE 3427554 C2 described type and nevertheless provide a bonding agent that causes a permanent tight fit on the body and other wear-resistant coatings of oxide ceramics or carbide securely fixed on the body.
  • the object underlying the invention is achieved by the coated body according to claim 1 and by the method according to claim 7.
  • the adhesion promoter layer consists of ductile metal selected from the group consisting of copper, lead and tin and applied by plasma spraying or flame spraying.
  • the adhesive layer of ductile metal is suitably applied in a thickness of 0.01 mm to 3.0 mm, preferably about 0.1 mm.
  • wear-protective layers of oxide ceramics such as chromium oxide (Cr 2 O 3 ), aluminum oxide (Al 2 O 3 ), titanium dioxide (TiO 2 ), quartz-containing mullite (eg 3Al 2 O 3 2SiO 2 to 2Al 2 O 3 - SiO 2 ), zirconium oxide (ZrO 2 ) and mixtures thereof, as well as wear-resistant hard metals, for example from the group tungsten carbide / cobalt (WC / Co), tungsten carbide / nickel (WC / Ni), titanium carbide / nickel (TiC / Ni), nickel-chromium / chromium carbide (Cr 3 C 2 / NiCr), nickel-chromium-boron-silicon (NiCrBSi), molten carbide (pure chromium carbide), chromium, molybdenum with oxygen, etc. preferably by thermal spraying methods such as plasma spraying, flame spraying and High speed flame spraying
  • outer coatings may also, as known ( EP 0 999 043 A1 ), get a non-stick seal.
  • the oxide ceramic or cemented carbide layer protecting against wear does not have to be applied by thermal spraying, but can also be applied by coating processes such as PVD (Physical Vapor Deposition), CVD (Chemical Vapor Deposition), sintering, hot isostatic pressing, electroplating, explosive plating, build-up welding, brazing, adhesive techniques or reactors be applied, provided that no delamination of the carbon fibers in the plastic matrix or damage the latter occurs.
  • PVD Physical Vapor Deposition
  • CVD Chemical Vapor Deposition
  • sintering hot isostatic pressing
  • electroplating electroplating
  • explosive plating build-up welding
  • brazing adhesive techniques or reactors be applied, provided that no delamination of the carbon fibers in the plastic matrix or damage the latter occurs.
  • the wear-resistant coating has a thickness of 0.01 to 3.0 mm, preferably 0.1 mm.
