Definitions

  • the phosphorus content has been increased, in some cases up to 1.5%, or small additions of chromium up to 1.5%, and of molybdenum or vanadium up to a few tenths of a percent, have been made. Wear has thus been reduced somewhat, but the braking effect was impaired, and to some extent, the braking surface of the wheel or tyre has been damaged.
  • This invention now consists in that a vehicle brake part subjected to stress by sliding friction is made of a highcarbon, austenitic iron alloy having a proportion of free carbon.
  • austenite formers-nickel and manganeseit has been found advantageous to add also a certain copper content, which dissolves in the austenite, and may amount to from about 0.5 to 4%. It is furthermore advantageous to imbed in the groundmass, in addition to austenite, hard constituents, such as carbides, phosphides and so forth.
  • hard constituents such as carbides, phosphides and so forth.
  • iron carbide and carbides of carbideforming elements such as chromium, molybdenum, vanadium, and titanium, as well as phosphorus.
  • the addition of chromium may amount to about 0.5 to 3%, that of molybdenum, vanadium and titanium each to about 0.1 to 1% and that of phosphorus to about 0.6 to 1.5%.
  • Part of the carbon is present in the alloy in the free form as lamellar or spheroidal graphite.
  • the latter form of graphite is obtained by treatment with the addition of magnesium or cerium or both.
  • Such an austenitic cast iron for brake parts has, for example, the following typical analysis:
  • the invention may be used not only for brake shoes, acting on the wheel rims of railway vehicles, but also for other brake parts, which are subjected to stress by sliding friction, for example for brake discs.
  • a vehicle frictional brake part subjected to stress by sliding friction consisting of a high-carbon, austenitic iron alloy having a proportion of free carbon.
  • a brake part according to claim 2 in which for austenite formation, part of the nickel has been replaced by manganese from 0.5% to 7%.
  • a brake part according to claim 1 in which the material contains 0.5 to 3% chromium.
  • a brake part according to claim 1 in which the material is subjected to a heat treatment by annealing between 800 C. and 1000 C.
  • a vehicle frictional brake part subjected to stress by sliding friction consisting of a high-carbon austenitic iron alloy having a proportion of free carbon, comprising the components nickel, carbon, silicon, copper, manganese, phosphorus, chromium, sulphur substantially in the proportions" 19%, 2.8%, 2.3%, 24.0%, 1.5%, 0.6%,
