Surface Modification of Aluminized Cu-10Fe Alloy by High Current Pulsed Electron Beam

Abstract

A Cu-10Fe alloy with magnetron sputtered Al films was irradiated by high current pulsed electron beam (HCPEB) with various pulse numbers, next changes of its microstructure and corrosion property were investigated. Compared with the initial sample, microhardness and corrosion resistance of the aluminized Cu-10Fe alloys after the HCPEB treatment are remarkably improved with increasing pulse numbers. This improvement could be attributed to formation of Al 2 Cu intermetallic compounds, occurrence of liquid phase separation and grain refinement in the surface layer of the Cu-10Fe alloy during the process of rapid remelting and solidification induced by the HCPEB treatment.

The Simulation of Emergency Action on Construction Materials by High Current Relativistic Electron Beams

“…The perspectives of this approach are in application of the coating under action of a pulsed electron beam, so internal stresses will be on par with the possible critical loads that might occur during operation. The beam method to create coatings may also be enhanced with an additional modifying effect on the coating, which was previously applied by another method [9]. The article [10] describes the methods using the effect of irradiation with a constant electron beam with high spatial accuracy leveraging a complex scanning system.…”
