Conclusions

  1. 1.

    We determined the optimal composition of the atmosphere for carbonitriding of malleable iron and gray cast iron to obtain the required thickness of the ε and γ zones and surface hardness of the coating.

     
  2. 2.

    A relationship was found between the depth of the individual zones and the carbonitriding temperature and time.

     
  3. 3.

    Gray cast iron carbonitrided at 700° has a high wear resistance under conditions of friction without lubrication under high loads.
