Abstract
Methods involving surface hardening of pieces by chemical and heat treatment are widely used to obtain high resistance to cyclic loading in construction steels. Among these methods, the processes of carbonitriding and carburizing are effective under large-scale assembly-line mass production conditions. At the same time, data available in the literature is insufficient for effective selection of the material and technological parameters providing high cyclic-loading strength and reliability of parts under heavy load.
