Abstract:

Polycrystalline pure copper was irradiated by High Current Pulsed Electron Beam (HCPEB) to investigate the effect of irradiation on pure copper. Both the surface microstructures and corrosion properties of pure copper before and after HCPEB treatment were studied in detail. Experimental results indicate that the corrosion resistance of pure copper irradiated by 10 pulses was remarkably improved according to the analysis of polarization curves of copper in seawater and electrode impedance spectroscope. Transmission Electron Microscopy (TEM) observations show that large amount of supersaturated vacancy defects were produced when the material surface was subjected to HCPEB irradiation. The agglomeration of vacancies can cause the formation of vacancy clusters, such as vacancy dislocation loops and Stacking Fault Tetrahedrons (SFTs). The vacancy clusters on the irradiated surface promotes the formation of a thick and dense passive surface layer, whose ability to bock the corrosive anions is enhanced, thus improving the corrosion resistance of the material.

Key words: metallic material, high current pulsed electron beam(HCPEB), pure copper, microstructure, anti-corrosion property
