Definitions

  • the invention relates to a blade bearing ring of a turbocharger with turbine blades adjustable in the blade bearing ring according to the preamble of patent claim 1.
  • a suitably suitable material must have a sufficient creep resistance, high dimensional stability, by which a thermal distortion is avoided even at high temperatures on the blade bearing ring, a high wear resistance and a sufficient oxidation resistance. If it comes to delay, creep or a strong oxidation of a generic blade bearing ring, this can lead to the blocking of the turbine vanes, that is, the turbocharger cross-section can no longer be adapted to the driving condition of the engine by a vane adjustment.
  • EP 1396620 discloses a turbocharger exhaust system including a vane bearing ring having improved heat resistance thanks to an alloy wherein the nonmetallic alloy components are not more than 0.1% by weight.
  • the invention is concerned with the problem of designing generic blade bearing rings materially reliable for use at extremely high temperatures.
  • a high creep resistance and high strength at temperatures above 850 ° C is desired.
  • the mobility of the turbine blades in the generic blade bearing ring should be absolutely guaranteed.
  • the invention is based on the general idea that in higher performance engines, in particular the creep resistance and strength of a blade bearing ring material, increased requirements are met by an austenitic iron material having a sulfur content causing a solid lubricant property to which high melting alloying elements are added, these alloying elements being present singly or in the presence several of these elements should occupy a proportion by weight of at least one percent by weight up to six percent by weight.
  • This diagram shows the coefficient of thermal expansion of alloys A and B as a function of temperature.
  • the ordinate represents the hot hardness (in HV10) as a function of the temperature for alloys A and B.
  • the ordinate shows the hardness (in HB 2.5 / 187.5) of the alloys A and B after 2 hours aging and air cooling as a function of the temperature.
