Conclusions

  1. 1.

    It is expedient to combine the sintering of materials formed from iron powder and mixtures of "iron/alloying-element" powders with the carburizing process; this simplifies the procedure and is economically useful.

     
  2. 2.

    Combination of the sintering and carbonizing processes contributes to improved mechanical properties of the materials: σu by a factor of 1.1–1.5, and α by a factor 1.2–1.6.

     
  3. 3.

    The combined treatment variant will make it possible to expand the range of application of powder articles and to modify their fabrication at establishment involved with series production, which have carburizing equipment.
