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 warping, creeping or severe oxidation of a generic blade bearing ring occurs, this can lead to blockage of the turbine guide vanes, ie the turbocharger cross section can no longer be adapted to the driving condition of the engine by a guide vane adjustment.
  • alloy PL 23 As blade bearing rings so far mainly ferritic materials containing a high proportion of chromium and chromium carbides are used.
  • austenitic materials containing chromium carbides are used.
  • Such an alloy is referred to below as alloy PL 23.
  • 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 high-performance engines, in particular the creep resistance and strength of a vane bearing ring material, increased requirements are met by an austenitic iron material with a sulfur content causing a solid lubricant property to which high-melting alloying elements have been added, these alloying elements being used singly or at a proportion of 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 HVlO) as a function of the temperature for alloys A and B.
  • Fig. 5 The ordinate shows the hardness (in HB 2, 5/187, 5) of alloys A and B after aging for 2 hours each and air cooling as a function of temperature.
