Abstract

Für thermisch hochbelastete Motorenteile wird eine Silicium und Molybdän enthaltende Gußeisen-Legierung mit Kugelgraphit vorgeschlagen. Um gegenüber dem Standard GGG-SiMo51 insbesondere eine wesentlich höhere Zunderbeständigkeit zu erreichen, die mit der einer GGG-NiSiCr 35.5.2 (Ni-Resist)-Legierung vergleichbar ist, wird vorgeschlagen, daß die Legierung:

  • 2,7 - 3,4 % C
  • 4,4 - 5,4 % Si
  • 0,4 - 1,2 % Ni
  • maximal 0,5 % Cr
  • 0,7 - 1,4 % Mo
  • maximal 0,5 % Mn
  • 0,03 - 0,08 % Mg
    • enthält.A spheroidal graphite cast iron alloy containing silicon and molybdenum is proposed for motor parts subject to high thermal loads. In order to achieve a significantly higher scale resistance compared to the GGG-SiMo51 standard, which is comparable to that of a GGG-NiSiCr 35.5.2 (Ni-Resist) alloy, it is proposed that the alloy:
  • 2.7-3.4% C
  • 4.4 - 5.4% Si
  • 0.4-1.2% Ni
  • maximum 0.5% Cr
  • 0.7 - 1.4% Mo
  • maximum 0.5% Mn
  • 0.03 - 0.08% Mg
    • contains.
