Definitions

  • the invention relates to a blade mounting ring on a turbocharger having turbine blades adjustable in the blade mounting ring according to the preamble of Patent claim 1 .
  • a suitable material must have a sufficient creep resistance, a high dimensional stability, which prevents thermal deformation of the blade mounting ring even at high temperatures, a high wear resistance and adequate oxidation resistance. If deformation, creep or heavy oxidation occurs on a generic blade mounting ring, it can result in locking of the turbine guide vanes, i.e., the turbocharger cross section can no longer be adapted to the driving performance of the engine by adjusting the guide vanes.
  • the present invention relates to the problem of designing the material for generic blade mounting rings so they are reliable in operation at extremely high temperatures.
  • a high creep resistance and a high strength at temperatures above 850° C. are desired in particular.
  • the mobility of the turbine blades in the generic blade mounting ring should be absolutely certain.
  • the invention is based on the general idea of fulfilling the strict demands of creep resistance and strength of a blade mounting ring material, in particular for high-performance engines by using an austenitic iron material having a sulfur content that yields a solid lubricant property, to which high-melting alloy elements are added, and these alloy elements should amount to a percent by weight between at least one percent by weight and up to six percent by weight.
  • An increased creep resistance of the blade mounting ring material that can be achieved according to this invention yields a high dimensional stability of the blade mounting rings at elevated temperatures. There is good lubrication on the contact surface between the blade mounting ring and a turbine blade mounted therein, in particular due to the effect of the solid lubricant, which is attributable to the sulfur content in the bearing. With the inventive use of materials, blocking of the turbine blades, i.e., the guide vanes at high temperatures, is reliably prevented.
  • the drawing shows some property diagrams for inventive blade mounting ring materials.
  • the curves labeled as A in the individual diagrams indicate a material according to claim 3 and the curves labeled as B indicate a material according to claim 4 .
  • the elastic modulus E and the shear modulus G of the alloys A and B are plotted as a function of temperature in this diagram.
  • This diagram shows the thermal expansion coefficients of alloys A and B as a function of temperature.
  • the hot hardness (in HV10) is plotted on the ordinate as a function of the temperature for alloys A and B.
