Definitions

  • the present invention relates to a method for producing a metallic component provided with a ceramic lining in a mold, a first ceramic layer being applied to this.
  • a method for producing a metallic component provided with a ceramic lining in a mold a first ceramic layer being applied to this.
  • the applicant has described a method by means of which castings made of metallic material can be provided with a cast-in smooth lining, e.g. so-called portliner of internal combustion engines.
  • layers are applied successively to a lost core by means of flame or plasma spraying, the composition of which is varied in such a way that a purely ceramic composition gradually becomes a finally purely metallic composition.
  • An arbitrarily thick layer of metal can be cast onto the latter to complete the component.
  • the graded transition from ceramic to metal leads to a gradual reduction of the stresses caused by the different thermal expansion of the two materials in the component.
  • JP-A 6 179 818 a method for producing a composite body is known, in which the different thermal expansions between the metal and the ceramic part are reduced by the fact that, as an intermediate layer, a grid or a fabric made of e.g. stainless steel or a ceramic fiber is introduced; penetration of the melted material into the grid is to be avoided in order to maintain the deformability required for the compensation.
  • this grid does not have a ductility leading to the different parts sliding off one another.
  • the object of the present invention is an alternative solution to the same technical problem, namely a coating of metallic components, preferably on the inside of those components that are hollow.
  • a sliding layer is first applied to the first ceramic layer; then a second ceramic layer divided into individual areas by joints; and finally in that the second ceramic layer is cast in a known manner with metal to form the finished component.
  • the first ceramic layer essentially forms the desired thermal protective layer and must be dimensioned with regard to its thickness and porosity; Layers (which can be produced using several conventional methods) of 2 to 3 mm thick (possibly composed of several partial layers applied one behind the other) appear suitable.
  • the sliding layer in turn only needs to have a thickness of 0.05 to 0.1 mm and, due to its ductility (which is also the case with the use of metal at these small thicknesses), reduces stresses by sliding the two ceramic layers against one another.
  • a layer thickness of 0.1 to 1 mm is recommended for the second ceramic layer. Splitting the same into numerous segments separated by joints of a few hundredths of a millimeter offers a possibility of reducing the stresses that occur after the coating of the metal has been cast around it by its greater thermal contraction during cooling by closing these joints. If the temperature rises again during operation, the second ceramic layer follows by opening it again.
  • a further embodiment of the invention teaches a method of how the required joints in the second ceramic layer can be produced in a defined size and frequency, namely in that they are specified by a grid placed on the sliding layer made of a material that is produced by the process of Applying the layer and / or burned or sublimed by the casting.
  • Various plastics appear suitable for the production of the grid.
  • Preferred materials for the production of the first ceramic layer are aluminum-titanium oxide, magnesium-aluminum-silicate, zirconium silicate or mullite. Like the materials proposed below for the second ceramic layer, they have a low modulus of elasticity, which dampens the transmission of vibrations to the metal parts.
  • the sliding layer consists of molybdenum disulfide or boron nitride.
  • Materials which are suitable according to the invention for the formation of the second ceramic layer and which have the required thermal shock resistance with good mechanical properties and sufficient chemical resistance are aluminum-titanium oxide, zirconium oxide / magnesium oxide, zirconium oxide / yttrium oxide, zirconium silicon oxide and magnesium aluminum -Silicate, aluminum oxide / silicon oxide, quartz material, mullite or spinel.
  • both the ceramic layers and the sliding layer are applied by plasma or flame spraying.
  • These closely related processes are particularly suitable for the production of thin, uniform layers on complexly shaped surfaces. They have a certain roughness on their free surface, which is conducive to better interlinking of the individual layers.
  • the method according to the invention appears particularly suitable for providing the inside of hollow bodies with ceramic protective layers.
  • a core made of glass is used, a very smooth inner surface of the coated component can be achieved. If low-melting metals are used, the glass can be replaced with a suitable plastic.
  • An embodiment of the invention is shown in the drawing, namely in longitudinal section using the example of the exhaust manifold of an internal combustion engine.
  • the thicknesses of the individual layers are greatly exaggerated for the sake of representability.
  • a lost core 1 made of glass was Plasma or flame spraying applied a first ceramic layer 2 several millimeters thick, then a very thin sliding layer 3 made of metal, boron nitride or molybdenum disulfide, and a second ceramic layer 4 on this in turn by the same method.
  • This is divided into individual fields by thin joints 5 ; the joints 5 represent the gaps left by the burning of a lattice that previously took their place.
  • B. cast aluminum or iron and subsequent destruction of the core 1, the component is completed.
