STRUCTURAL-PHASE STATE OF THE SURFACE LAYER OF AI-SI ALLOY AFTER ELECTRON-ION-PLASMA TREATMENT

Abstract

The results of silumin surface modification by combined method including irradiation by plasma produced in the electric explosion of conductive material followed by a pulsed electron beam treatment are presented. The formation of a multilayer polyphase sub-micro and nanoscale structure with high mechanical and tribological properties is revealed. The results obtained are discussed from the viewpoint of thermodynamics.
