Conclusions

  1. 1.

    The wear resistance of carburized and nitrided cases on 18KhGT steel is approximately the same, which is probably the result of the closeness of the hardnesses of these cases.

  2. 2.

    For the surface and near-surface zones of the nitrided and carburized cases a higher wear resistance than that of the deeper zones is, as a rule, characteristic.

  3. 3.

    The maximum surface pressure for carburized and nitrided cases on 18KhGT steel must be less than 400 MPa. With a pressure of 400 MPa and more seizing of the cases of both types is observed.

  4. 4.

    With a certain allowable wear of the parts during service carburized cases on 18KhGT steel may be replaced by nitrided.
