Investigation of the thermal processes in electron-beam surface modification by means of a scanning electron beam

Abstract

In this work we present a study of the thermal processes taking place during surface modification of steels performed by a scanning electron beam. The model is based on solving the heat transfer equation by means of Green functions. The thermal field was calculated, together with the size of the zone of structural changes in tool steel samples. The comparison of the zones of thermal treatment as experimentally obtained and theoretically calculated and the corresponding structural changes show a very good agreement.
