Definitions

  • the invention relates to a sealing ring, in particular a shaft seal for a turbocharger.
  • the material of the sealing ring in particular of a shaft sealing ring, must have different properties in order in particular to be able to guarantee a sealing function over the entire service life of the turbocharger.
  • the sealing function is influenced mainly by a wear resistance or a creep of the sealing rings, so that in addition to high wear resistance and a sufficiently high creep resistance is required especially for new and highly loaded turbochargers, for example for gasoline engines.
  • the materials used hitherto for such sealing rings, in particular tool steels, are not sufficient for their creep resistance, while austenitic materials or nickel-based alloys often do not have sufficient wear resistance.
  • the invention is concerned with the problem of providing an improved embodiment for a sealing ring, which in particular overcomes the disadvantages known from the prior art.
  • the invention is based on the general idea of using a base material based on iron or on a nickel-based alloy for a sealing ring, in particular for a shaft seal of a turbocharger, and boring the sealing ring.
  • Boriding is understood as meaning a thermochemical surface hardening process for producing a wear-resistant surface on a workpiece, wherein boron causes the chemical element boron to be introduced into the edge zone of a material, here into the edge zone of the sealing ring, at a temperature between 850 and 950 ° C. This forms a Borid harsh up to a depth of about 250 microns, which causes a surprisingly good anchoring to the base material of the sealing ring.
  • boriding on the one hand achieves high wear resistance and, on the other hand, high creep resistance of the material.
  • boriding makes it possible to use the sealing rings under high mechanical and tribological loads at temperatures of up to 850 ° C.
  • wear protection layers which are applied, for example, by a PVD process
  • the boriding effect significantly improves anchoring of the wear protection layer to the base material of the sealing ring.
  • This surprisingly good connection between the base material and the wear protection layer (Borid Anlagen) prevents a flaking of the same during assembly of the shaft seals on the associated shaft, in which the shaft seals must be bent usually.
  • the hardness and thus brittle fracture tendency can be reduced with the boriding invention, so that significantly less waste during assembly and thus a significantly improved efficiency are expected.
  • the borated shaft seals can also be hardened to limit the relaxation in the assembled state.
  • the hardness of borated rotary shaft seals may be, for example, less than 60 HRC, preferably about 45 HRC.
  • Such a surprisingly good connection between the wear protection layer and the base material can not be achieved with other surface hardening methods, for example nitriding.
  • nitriding cracks may occur along the diffusion boundary between the nitride layer and the base material due to the poorer toothing / connection between the nitride layer and the base material during the bending of the shaft sealing rings, which cause a break-off of the nitride layer and thus destruction of the wear protection layer.
  • the boride layer may crack.
  • the iron-based base material is at least partially austenitic.
  • Austenite refers to ⁇ mixed crystals of iron, with austenite usually having a cubic surface centered structure.
  • the structure itself has a low hardness, which, however, can be increased for example by cold deformation.
  • the iron-based base material is at least partially martensitic.
  • Martensite is a metastable structure of solids that is non-diffusion and athermal due to a cooperative shear motion arises from the initial structure.
  • the carbon dissolved in austenite can be forcibly dissolved by a very rapid cooling, for example during quenching, resulting in a very hard structure.
  • the cooling rate at which first fractions of martensite, next to ferrite, pearlite and bainite, is called the lower critical cooling rate.
  • martensite is used in steels to achieve a hardness increase. The higher the carbon content of martensite, the higher its hardness.
  • the iron-based base material is at least partially bainitic. Bainite forms at temperatures which are between those for the formation of pearlite and martensite. In contrast to the formation of pure martensite, folding processes in the crystal lattice and diffusion processes are coupled here, which makes various conversion mechanisms possible.
