On restrictions in the problem of optimum control process of gas nitriding
The aspects of statement the management problems of gas nitriding process are considered. Research of the system communications providing the main purpose of this type of chemical heat treatment namely the improvement of operational characteristics of the processed products is conducted. Inadmissible areas in space of states are established. Restrictions on concentration of nitrogen in phases, on surface temperature of the heated body, on thermal stresses and on extreme values of nitric potentials of the atmosphere are formulated.
