✦ Synopsis

The objective of this study was to identify the significant conditions to provide electron beam surface hardening of heat treatable carbon steel. Computer modelling to determine the dependence of surface hardness and hardened layer thickness on the electron beam energy density is presented. Using swept line electron beam hardening in an installation developed for carrying out experiments on surface hardening, the experimental results were in good agreement with those from calculations and confirm that it is impossible to assess the hardened layer thickness and uniformity or to find the most suitable processing conditions by measuring the mean value of surface hardness only. The detailed investigation of cross-sections is indispensable.

The experimental design applied in this paper has proved to be a useful statistical tool for optimizing electron beam surface hardening.
