摘要：

为考察辐照对纯铜材料的影响,利用强流脉冲电子束(HCPEB)技术对多晶纯铜进行表面辐照处理,详细考察了辐照前后材料表面的微观结构状态和腐蚀性能。海水腐蚀极化曲线及电极化阻抗谱实验结果表明:十次强流脉冲电子束辐照后,纯铜的抗腐蚀性能显著提高。透射电子显微镜观察表明,HCPEB辐照在材料表层诱发了大量的过饱和空位缺陷,空位缺陷的凝聚可形成空位型位错圈和堆垛层错四面体(SFT)等空位簇缺陷。空位簇缺陷有助于形成厚而致密的表面钝化膜,钝化膜具有阻挡腐蚀性阴离子的能力,从而提高材料的抗腐蚀性能。

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
