Definitions

  • the invention relates to a method for producing ceramic / metal composite layers by spraying and to a coating material therefor.
  • the layer thickness of the ceramic coating depends on the insulation requirements, but due to the high temperature stresses that can occur in the ceramic material, the layer thickness of a ceramic coating is very limited.
  • pure ceramic layers with a thicker layer thickness can be produced using the plasma spraying process.
  • the material applied to a substrate has very high temperatures and a low temperature gradient in this process, so that any tensions in the still liquid areas can be reduced.
  • these layers are not stable in the event of particularly strong temperature changes.
  • the layer thickness limit can be extended with a composite coating of ceramic and metal.
  • a ceramic layer is first applied and then a metal layer.
  • this known method requires two operations.
  • the invention has for its object to provide a method of the type mentioned, with which a durable ceramic / metal layer can be applied to a substrate with as little work as possible.
  • the ceramic material being able to be processed at a lower temperature than in the known methods after it has been embedded in the softer metal on the substrate.
  • the two components namely the metal and the ceramic material
  • the two components are mixed within the entire layer, so that, in addition, a better absorption of tensile forces by the metal can take place than is possible with the successive coating of ceramic and metal.
  • such a layer has a high physical, mechanical and chemical resistance. It is therefore not only suitable for the production of thermal insulation layers, but also for wear-resistant top layers.
  • the metal is fed to the spraying process in the form embedded in the ceramic material.
  • Preparation of the coating material in the form of a ceramic tube with a metal or metal-containing core is preferably proposed.
  • This composite coating material is made in a simple form by drawing ceramic pipes and filling them with the appropriate metal.
  • the metal or a metal-containing material can be introduced into the ceramic tube as powder, in liquid form or as wire.
  • a coating material prepared in this way has many advantages.
  • an endless loop can be made by lining up ceramic tube pieces.
  • the wire and the ceramic tube can - if necessary or appropriate for a specific application - be driven at different feed speeds.
  • the concentration in the coating is achieved by changing the concentration of a core material consisting of metal and ceramic material or by changing the relative feed between core material and ceramic tube.
  • the ceramic tube also serves as heat insulation for the metal, so that it is not heated up to the evaporation temperature. It was found that the material is removed from the rod in a similar form to a sharpened pencil, with ceramic and metal being applied to the substrate at the same time.
  • the coating material is a rod 12 consisting of a ceramic tube 10, e.g. made of aluminum oxide, zirconium oxide with a metal core 11, e.g. made of Co, CrNi, metal / ceramic material, which is melted in a spraying device 13. With the help of a gaseous fluid 14, the melted composite material is applied to a substrate 15.
  • the rod 12 is heated within the spray device 13 to a temperature which causes the ceramic material 10 to melt. Insulated by the ceramic tube 10, the metal core 11 does not heat up to the externally applied temperature, but to a lower temperature which is sufficient around the metal to melt, but not to evaporate.
  • the removal of the coating material takes place at the tip 16 of the rod with a conical shape, so that when the ceramic material is removed from the tip, liquid metal can be drawn along.
