Definitions

  • the invention relates to a method for coating molded parts made of fiber composite materials with refractory materials such as metal, ceramic or combinations of these materials according to the preamble of the claim.
  • DE-PS 31 36 283 describes a method for evaporating the surface of carbon fiber reinforced plastic parts e.g. known with aluminum, in which the plastic matrix is removed in the course of the pretreatment until the carbon fibers are partially exposed. This gives good adhesion between the plastic part and the evaporated metal.
  • the application of this method is limited to a relatively small number of metallic materials.
  • DE-OS 35 27 912 discloses a method in which plasma-sprayed coatings are applied to a molded part made of fiber composite material using phenol formaldehyde as the matrix material.
  • the area of application of this method is very limited, since only molded parts with low demands on strength and stretchability can be produced with the proposed matrix material. This document points out that other matrix materials have failed because they chemically decompose and change in volume.
  • EP-PS 0 124 432 describes a method for coating a workpiece by means of a plasma jet, in which the workpiece is cooled with the aid of a liquid gas. It should also be possible to coat materials that become unstable at over 120 ° C. On the other hand, fiber composite materials, for example, have a relatively low thermal conductivity, so that there is a risk of local overheating, which can impair the dimensional stability and the strength of workpieces made from such materials.
  • the invention has for its object to provide a coating method of the generic type, with which molded parts made of fiber composite materials can be coated with a large number of different high-melting materials such as metals, ceramic materials and their combinations with high adhesive strength without impairing the dimensional stability and strength as a result of insufficient cooling .
  • molded parts made of fiber composite material in addition to metals such as Al, Cu, Ni, Co, NiCrBSi alloys, also with ceramic or metal-ceramic materials such as Al2O3 / TiO2, ZrO2 / Y2O3 as well as carbidic materials such as WC / Co compared to fiber composite materials with a plastic matrix have very high melting temperatures of up to 3000 ° C.
  • the process can be used for composite materials with all common fiber materials such as carbon, glass, aramid, boron and matrix systems such as epoxy, polyester and polyimide resins.
  • all common fiber materials such as carbon, glass, aramid, boron and matrix systems
  • matrix systems such as epoxy, polyester and polyimide resins.
  • the layer thicknesses can range from about 50 ⁇ m to a few 100 ⁇ m without the build-up of tension in the transition zone between the fiber composite and coating material.
  • the inner surface is first treated with high-grade corundum using compressed air radiation and then blown off with CO2 at 60 bar in order to remove loose particles.
  • the molded part cools below room temperature.
  • the inner and outer surfaces of the containment shell are applied by means of CO2 gas jets which emerge from a plurality of nozzles at a pressure of 60 bar.
  • the plasma jet is enveloped by a cooling gas stream made from argon and another cooling gas stream made from CO2.
  • the coated inner surface remains below the glass transition temperature of the plastic of approximately 150 ° C., so that no thermal decomposition phenomena and associated volume changes in the matrix of the fiber composite material occur.
  • the Plasma spraying moves the plasma jet and the molded part against each other.
  • the outer surfaces of such hollow bodies or also plate-shaped molded parts can be coated.
  • Plasma spraying can be carried out in an atmospheric environment.
