The article suggests a model that allows to make theoretical evaluation of the depth of the modified layer of austenitic 06Х19Н9Т steel after ion beam nitriding. The number of pinholes generated during the processing and the time of saturation have been selected as parameters exerting a major influence on the depth of penetration of nitrogen into steel during ion beam processing. The article presents model calculations of the depth of modified layer for different temperature ion-beam nitriding of austenitic 06Х19Н9Т steel.
