Utilization of high power ion beams and high current electron beams for modification of metalline materials

The brief review of results on the application of high power ion beams (HPIB) and high current electron beams (HCEB) for the modification of metalline materials and mixing of refractory films deposited to the metalline substrate is presented. The main factors of HPIB and HCEB treatment affecting the structure phase transitions, defect formation in the surface and inside the substrate are: the fast quenching from liquid and solid states, the formation of elastic, plastic and shock waves, the formation of stress gradients and the mass transfer during liquid and solid phases. The examples of HPIB application for modification and mixing in hermetically sealed ferreed contacts resulting in improving the electro-erosion resistance and resistance; and of HCEB application for hardening, wear decreasing, increasing the corrosion resistance and decreasing the brittle damaging ability are demonstrated.
