Effect of rate of dose build-up of manganese ions on changes in mechanical properties, morphology, and composition of surface layers of carbon steel

The effect of a dose build-up rate of 5 × 1016 ion/cm2 under irradiation with manganese ions with an energy of 45 keV and at a current density of 10–50 μA/cm2 on the mechanical properties, morphology, and composition of the surface layers of carbon steel St3sp has been investigated. It is shown that, among the dose build-up rates used, the optimal rate for surface hardening corresponds to an ion-current density of 10 μA/cm2. Based on these experimental data, a model of the processes that occur during the implantation of steel with Mn ions has been proposed.
