Conclusions

  1. 1.

    A study was made of the antifriction properties of sintered constructional chromium and carbon steels and, for comparison, of ShKh15 steel in rubbing without lubrication against R9 steel.

  2. 2.

    With increase in sliding velocity, the coefficient of friction in the operation of all the materials investigated was found to decrease, while their wear increased.

  3. 3.

    The highest wear resistance of all the materials tested was shown by ZhCh25Kh3 sintered chromium steel.

A stable coefficient of friction in the testing of the sintered materials was established only at sliding velocities above 2 m/sec. The least coefficient of friction, 0.38, was exhibited by ZhCh25Kh3 steel at sliding velocities of 2–4 m/sec. The coefficient of friction in the testing of ShKh15 steel under the same conditions was 0.45–0.56.

  1. 4.

    The antifriction properties of sintered chromium steels are greatly superior to those of sintered unalloyed steels. The antifriction properties of sintered materials improve as their carbon content is raised up to a certain limit.
