The authors determine the relationship between alpha and structural parameters of the boride layer. The authors used specimens of carbon steels 20, 45, and U8A, since under certain impregnation conditions thickness and structure of the boride layer depend mainly on carbon content in the steel. By means of chromatic etching it was established that with impregnation in a bath with boron carbide at 850/sup 0/ for 5 h and 950/sup 0/ for 3 and 5 h, a two-phase boride layer (FeB + Fe/sub 2/B) forms on the steels. As a result of boriding, there is a marked reduction in alpha for the steels. An equation used for developing the thermoelectric method of determining boride layer thickness on carbon steels is less labor consuming as compared to metallography.
