  1. 1.

    The proposed criteria for evaluating the quality of carburized and carbonitrided cases and also the method of determination of their interrelationship with the production parameters of chemicothermal treatment guarantee development of high quality hardened cases on machine parts.

  2. 2.

    Microstructural diagrams of hardenability of the impregnated layer may be used for evaluating its quality and selection of the type of steel and the optimum chemicothermal treatment cycles with the specified conditions of hardening of parts. Such diagrams are also useful for predicting the mechanical properties of finished parts and may be used in automated control of chemicothermal treatment production operations for tractor and truck transmission parts.
