Definitions

  • the present invention dispenses with a consistently high nitrogen content in the steel. Instead, only the edge zone of near-net shape parts made of stainless steel are enriched with dissolved nitrogen by heat treatment to such an extent that a high-strength but tough austenitic surface layer forms over a core structure made of ferrite, austenite, martensite or a mixture of two or three of these structural components.
  • the heat treatment according to the invention consists of nitriding in a nitrogen-emitting gas atmosphere at a temperature between 1000 and 1200 ° C.
  • the temperature, pressure and duration of the treatment are chosen so that an edge layer of a certain thickness is formed, the nitrogen content of which in the surface is between a lower limit of 0.3% by weight and an upper limit which is given by the beginning nitride precipitation during the nitriding.
  • the subsequent cooling takes place so quickly that nitride excretion does not occur in this period either.
  • Subsequent aging at a temperature of ⁇ 650 ° C enables the surface layer to harden.
  • Patent DE 40 33 706 describes case hardening with nitrogen, in which after a martensitic, rustproof steel is embroidered, a hard martensitic surface layer is produced over a ductile core by hardening. This process is used for the treatment of rustproof rolling bearings, gear parts and tools as well as for rustproof pump parts and valves in particle-laden fluids. In all these cases, the highest compressive strength and hardness of the surface layer are important, but this is associated with considerable embrittlement.
  • the aim of the present invention is to create a high-strength but tough austenitic surface layer over a ductile or hard core (Fig. 1).
  • the austenitic surface layer according to the invention is suitable for increasing the wear resistance, in particular when subjected to impact wear, cavitation and droplet impact, such as those e.g. occurs in turbomachines.
  • ferritic-austenitic duplex stainless steels are often used, the two-phase structure of which has the required high plug-in limit.
  • a common type of failure is wear due to cavitation.
  • a content of ⁇ 1.4% by weight of nitrogen is dissolved in the edge zone of this material by embroidering in nitrogen gas at 1150 ° C. and a pressure of 1 bar.
  • FIG. 3 This surface layer was subjected to a cavitation wear test in comparison to the core material not embroidered on.
