Abstract
The physicochemical processes entailed in carburization are distinguished by their complexity and instability. When such treatment is to be carried out under industrial conditions, it requires operative information on the distribution of the diffusing element across the metallic layer that is being saturated. This information is particularly important in automated technological processes. Timely correction of the technological parameters of carburization helps attain a stabler level of the strength properties of the treated components. The article suggests a method of checking the distribution of carbon across the carburized layer in steel by measurement of the thermo-emf. It presents the results of investigations of the steels 12KhN3A, 20Kh2N4A, 18KhGT after different kinds of heat treatment. The accuracy of determining the carbon content of the layer is not poorer than 0.08%.
