Definitions

  • the invention relates to a heat-resistant bearing material consisting of an austenitic iron matrix alloy, and here addresses the problem of making such a bearing material functionally reliable for use at high temperatures, especially at temperatures exceeding 600° C., in particular exceeding 850° C.
  • the bearing material here is to exhibit solid lubricant properties, which are to be retained at the specified high temperatures to as high a degree as possible.
  • the invention is based on the general idea of providing sulfur in a percentage amount that allows sulfides required for a lubricating effect to form within the alloy.
  • Such a formation of sulfide within an austenitic matrix alloy intended to exhibit a high creep resistance and high strength at high temperatures is a contradiction in and of itself. This contradiction stems from the fact that, based on general expert knowledge, sulfides contained in such a material are disadvantageous for a high creep resistance and high strength at high temperatures because they constitute a structural disturbance, and must therefore be avoided.
  • the invention proposes something that runs absolutely counter to general expert knowledge with respect to the objective of obtaining a material that is highly creep resistant and strong in terms of temperature, and still exhibits lubricating properties even at high temperatures, and hence represents a surprising result not to be expected by an expert.
  • the drawing shows a few diagrams depicting characteristics for bearing materials according to the invention.
  • the curves denoted in individual diagrams relate to a material according to claim 7 if marked A, and a material according to claim 8 if marked B.
  • This diagram records the modulus of elasticity E and sheer modulus G for alloys A and B as a function of temperature.
  • This diagram depicts the thermal expansion coefficient for alloys A and B as a function of temperature.
  • This diagram records the hot hardness (in HV10) on the ordinate as a function of the temperature for alloys A and B.
  • the ordinate shows the hardness (in HB 2.5/187.5) for alloys A and B after stored for a respective 2 hours and air-cooled as a function of temperature.
