Definitions

  • the invention relates to a press-cast light metal piston for internal combustion engines with fiber molded bodies made of short ceramic fibers, in particular made of aluminum oxide, silicon carbide or silicon nitride, which are partially cast into the piston crown, ring field, pin boss and / or piston skirt, and which are aligned parallel to a plane, but are statistically randomly oriented within this plane.
  • the comparatively low density of magnesium or its alloys has always given an incentive to test use pistons made from them in internal combustion engines in order to reduce the oscillating masses of the internal combustion engine and to lower the bearing pressures due to the relatively lighter piston.
  • Magnesium materials have compared to those usually used for the production of light metal pistons Internal combustion engines used aluminum-silicon alloys quite considerable disadvantages.
  • the lifespan of pistons made of magnesium materials is relatively short and their strength is relatively low compared to the dynamic stress caused by the gas forces.
  • DE 20 46 862 A describes the running surface of the piston, which is made of magnesium material, with a wear-resistant metallic running layer, e.g. Chrome, which should adhere firmly to the piston body via an intermediate layer of aluminum. It is also known to provide the tread with a wear-resistant coating made of aluminum alloy, iron, graphite, manganese, nickel, tin, lead, cadmium and zinc or to alloy magnesium with wear-resistant elements such as aluminum or silicon. To improve the strength, magnesium is alloyed with cerium and thorium and the piston is made by forging with appropriate guidance of the fiber orientation (company writing: Mahle KG and Elektron-Co. MbH, Stuttgart-Bad Canstadt, 1946).
  • a piston for internal combustion engines is known from JP 63-042 338 A, which consists of a magnesium alloy reinforced with 3 to 30% by volume of aluminum oxide-silicon oxide fibers.
  • JP 63-042 338 A which consists of a magnesium alloy reinforced with 3 to 30% by volume of aluminum oxide-silicon oxide fibers.
  • the piston is made of a heat-resistant magnesium alloy
  • the piston skirt has at least in the area of its friction surfaces a 10 to 30 ⁇ m thick, hardness of 740 to 850 HV 0.01 possessing metallic, chemically or galvanically deposited running layer and the inside of the piston is coated with a thin layer of plastic lacquer.
  • the selectively fiber-reinforced light metal piston made of a magnesium alloy By producing the selectively fiber-reinforced light metal piston made of a magnesium alloy by means of the injection molding process, a fine structure and thus a good temperature change resistance of the magnesium alloy can be achieved.
  • the use of preformed fiber bodies leads to an increase in the strength values, a reduction in the thermal expansion and an increase in the modulus of elasticity.
  • materials for the overlay nickel, cobalt, chromium, iron, nickel with cobalt inclusions or nickel with chromium inclusions, in particular, are considered within the scope of the further embodiment of the invention, which show high wear resistance and adhere firmly to the magnesium material of the piston body. Only in the event of extreme stress from the gas forces can it be appropriate to connect the metallic running layer to the magnesium material of the piston body via an intermediate layer made of copper.
  • particles of non-metallic hard materials such as silicon carbide or the like, or oxide-ceramic materials, such as chromium oxide or the like, can be found in the metallic running layer. be stored, which increases the wear resistance.
  • the thin plastic lacquer layer applied to the inside of the piston is completely or partially replaced by a magnesium oxide layer generated by anodic oxidation.
  • a magnesium alloy which contains 2 to 6 wt.%, Preferably 3.5 to 5.5 wt.% Neodymium is particularly suitable for the purpose according to the invention.
  • the magnesium alloy can also contain 0.5 to 7.5% by weight of yttrium in order to achieve higher hardening.
  • the invention is illustrated in more detail and by way of example on the basis of a longitudinal section along the plane enclosing the piston axis and the axis perpendicular to the pin axis direction through a piston (1) produced from a magnesium alloy of the material group Mg5Nd by die casting, the shaft of which is reinforced with 20 vol 16 to 24 ⁇ m thick chemically deposited nickel layer (3) and the inside of which are coated with a 15 ⁇ m thick plastic lacquer layer (2).
  • the relatively smooth nickel layer has neither pores nor cracks in the layer itself or in the connection zone with the magnesium alloy of the piston body.
  • the average hardness of the nickel layer is 740 to 770 HV 0.010 . To test the adhesive strength of the nickel layer, it was blasted with glass beads for 20 s. Detachment of the nickel layer could not be observed.
