Antifriction properties of iron-base sintered materials in dry friction

Summary

  1. 1.

    The load-carrying capacity of sintered iron/graphite composites is increased by alloying with copper and zinc sulfide. The seizure pressure is increased from 5 to 50–60 kg/cm2, the friction is stabilized and there is a 4–5 fold reduction in friction coefficient.

  2. 2.

    Iron-base compositions containing 1.5% graphite, 2% copper and 8–10% zinc sulfide may be recommended for service under dry friction conditions in contact with steel 45.

  3. 3.

    The results of examination of the friction surfaces on a fluorescent microscope indicate that the reduced wear and friction coefficients of materials containing zinc sulfide is attributable to the formation of a surface sulfide film.
