Definitions

  • the present invention relates to a piston ring used in an internal combustion engine, particularly, a piston ring consisting of high chromium martensitic stainless steel with nitriding, having improved scuffing resistance (seizure resistance), cracking resistance (failure resistance) and fatigue resistance.
  • the present invention is also related to a production method of the piston ring.
  • High chromium martensitic stainless steel mainly used at present for the piston ring with nitriding is JIS SUS440B equivalent composition of C: 0.80 -0.95%, Cr: 17.0-18.0%; Si: 0.25-0.50%; Mn: 0.25-0.40%; Mo: 0.70-1.25%; V: 0.07-0.15%; and Fe in balance.
  • the nitrides in the nitriding layer are mainly compounds of Cr, V and Mo, which may contain the solute Fe. Chromium which is the main component of this steel, is dissolved in the iron matrix, and is also present in the form of Cr carbides.
  • Cr is a substitutional solute element in Fe. Cr not only improves the corrosion resistance but also induces the solution strengthening and hence improvement in the thermal setting resistance.
  • the thermal setting is a phenomenon that sealing property is deteriorated by tension decrease due to creep during operation of a piston ring at high temperature.
  • Cr reacts with C in steel and forms Cr carbides. These Cr carbides easily react with N, which intrudes from the surface during nitriding, and are converted to Cr nitrides.
  • the Cr nitrides are dispersed in the nitriding layer as the hard particles. The hard particles in the nitriding layer exceedingly enhance the wear resistance and the scuffing resistance of the sliding surface of a piston ring.
  • the super saturated C and N precipitate around the primary ⁇ grains in the form of lamellar M 23 C 6 and M 2 N precipitates.
  • the N content is less than 0.05%, the ⁇ phase crystallizes.
  • the N content is more than 0.50%, the amount of M 2 N precipitates in the form of a rod increases, so that the toughness is lowered.
  • the N content is, therefore. in a range of from 0.05 to 0.50%, more preferably in a range of from 0.10 to 0.30%.
  • the solute N in the matrix impedes the diffusion of C and also contributes to refining of the grain boundary compounds.
  • FIG. 3 a scuffing test sample in the form of Japanese katakana “]” having 45 mm of the total length is shown.
  • the wire material was shaped into scuffing test samples of two-pin integral type.
  • the opposite material was made of FC250 and was in the form of a disc of 60 mm in diameter and 12 mm in thickness.
