Definitions

  • the invention relates to a multi-layer wall according to the preamble of claim 1.
  • the invention further relates to methods for producing the multi-layer wall according to the invention.
  • the object of the invention is to provide a multi-layered wall, which is thermally and mechanically highly resilient and, if desired, has good thermal insulation.
  • the invention consists in that the multilayer hollow body wall is constructed as indicated in the characterizing part of claim 1.
  • the ceramic inner layer mentioned there or its ceramic material is of the type that it can withstand high temperatures and / or large wear or large friction.
  • the holding layer or its fiber-reinforced material is of the type that it gives the wall great strength or strengths of a type other than wear resistance, in particular great tensile strength, preferably for absorbing a pressure of a fluid located in the interior of the hollow body.
  • the relevant tensile forces (they point in the circumferential direction in the case of the hollow body of revolution) are absorbed by reinforcing fibers of this holding layer, which are then under longitudinal fiber tension due to these tensile forces.
  • Such reinforcing fibers are in particular circumferential fibers, ie reinforcing fibers wound or running in the circumferential direction.
  • Reinforcing fibers which cross at an angle to the circumferential direction can also be provided. It is the ceramic inner layer through this holding layer under pressure preload (the relevant compressive forces point in the hollow revolution body in the circumferential direction), so that much higher internal pressures are tolerated than with a hollow body whose wall consists only of ceramic material. The ceramic inner layer is then not subjected to too much tension under internal pressure, which it might not be able to withstand.
  • the compressive stress mentioned can also be made so large that the ceramic inner layer is only under compressive stress at lower internal pressures; It can withstand compressive stress better than tensile stress.
  • this holding layer can have a high modulus of elasticity, an extremely low thermal expansion and a relatively high temperature resistance.
  • the strength of the metal holding layer is often smaller and the thermal expansion there is often greater than in the case of fiber-reinforced materials, which also applies to high-temperature steel as the preferred holding layer metal - see claim 4 can.
  • the insulating ceramic intermediate layer is provided.
  • the ceramic materials of the ceramic inner layer mentioned in claim 3 have high temperature resistance and high wear or abrasion resistance, and - see claim 5 - carbon fiber reinforced graphite for the holding layer has high tensile strength.
  • the materials specified in claim 6 for the intermediate layer are good heat insulation.
  • the fiber-reinforced material (embedding material, matrix) of the holding layer is in particular organic material or metal.
  • the invention is particularly in a diesel engine pre-combustion chamber, an internal combustion engine cylinder liner, a housing or housing part in contact with hot gas, a rolling bearing ring and a plain bearing, for. B. applied to bearing shells of the same, as a hollow body.
  • These devices or parts are thermally and mechanically stressed (in particular by the internal pressure and / or friction mentioned). Furthermore, good thermal insulation is usually desired with them, especially in the case of the above-mentioned pre-combustion chamber and the cylinder liner mentioned to keep the losses of the engine small.
  • the pre-combustion chamber 22 and the cylinder liner 23 are hollow revolution bodies.
  • the pre-combustion chamber 22 is located in a bore of a cylinder head 13 made of steel. It or its waird consists of a heat-resistant, ceramic inner layer 10 made of silicon carbide (SiC), an insulating ceramic layer 11 made of magnesium aluminum silicate (MAS) and a holding layer 12 made of carbon fiber reinforced graphite.
  • SiC silicon carbide
  • MAS magnesium aluminum silicate
  • the ceramic inner layer 10 extends, as seen towards the cylinder liner 23, so that the interior of the pre-combustion chamber 22 first narrows in the shape of a truncated cone, then, in order to form a bulbous combustion chamber 19, widens in the shape of a truncated cone and then contracts like a basin in order to subsequently run cylindrically.
  • the holding layer 12 or thus the pre-combustion chamber 22 is cylindrical on the outside along the two truncated cones, in order then also to contract like a basin and then to run cylindrical.
  • the cylinder head bore mentioned has the same shape and the same dimensions.
  • the pre-combustion chamber 22 is composed of three axially successive parts so that the holding layer 12 can be applied, the part planes being at the collision of the two truncated cones and with the large basin diameter.
  • the ceramic inner layer 10 is produced as a solid part
  • the insulating ceramic intermediate layer 11 is produced by applying a layer of sinterable insulating ceramic powder made of magnesium aluminum silicate (rIAS) to the ceramic inner body 10 by isostatic pressing or by overmolding (injection molding) and sintering this powder layer, and the holding layer 12 produced as a solid part and shrunk onto the insulating ceramic intermediate layer 11.
  • rIAS magnesium aluminum silicate
  • the cylinder liner 23 is a hollow cylinder body and is seated in an engine block 21, to which, not shown, the cylinder head 13 is screwed.
  • the cylinder liner 23 or its wall consists of a heat and wear or abrasion resistant, ceramic inner layer 16 made of silicon carbide (SiC), an insulating ceramic layer 17 made of aluminum titanate (A1Ti0 3 ) and a holding layer 18 made of high-temperature steel.
  • the layers 16 and 17 are manufactured individually as solid parts, and the part 17 is shrunk onto the part 16.
  • the holding layer 18 is then produced by applying a sinterable powder made of high-temperature steel to the part 17 by isostatic pressing or by overmolding (injection molding) and sintering this powder layer.
  • the finished MAS layer is machined so that a SiC tube with a
  • the outer layer is approximately 5 mm thick and is made of MAS
  • This composite body made of ceramic inner and MAS intermediate layer is now wrapped with a 5 mm thick layer of carbon fibers in the circumferential direction and impregnated with resin (phenols, polyimides, polyphenylenes) suitable for residue coking.
  • the resin is coked with the exclusion of oxygen (usually under a protective gas) at temperatures up to 1000 ° C.
  • the impregnation and coking are repeated two to five times, followed by graphitization by heating under protective gas at 2000 ° C.
  • Carbon fiber can also be used with boron carbide coated boron fibers in a matrix of aluminum, with preference as aluminum 6061 F or aluminum 2024 F is used. In this case, heat treatment is carried out at a temperature of 560 ° C under a working pressure of 15 bar.
