摘要： 利用强流脉冲电子束(HCPEB)对固溶态Mg-Gd-Y-Nd合金进行表面辐照处理。利用X射线衍射仪(XRD)、光学显微镜(OM)、扫描电子显微镜(SEM)对辐照前后样品的微观结构进行表征,并考察了 HCPEB 辐照处理后样品表面的显微硬度和腐蚀性能。实验结果表明:HCPEB处理后样品表面发生重熔并形成表面熔坑,随着脉冲次数的增加,熔坑密度逐渐减小;HCPEB处理后样品表面显微硬度显著提高。此外,电化学实验结果表明HCPEB表面处理后Mg-Gd-Y-Nd合金表面的抗腐蚀性能也得到明显的改善。表层晶粒细化、重熔层的形成和稀土元素的固溶强化效应是硬度提高和腐蚀性能改善的主要原因。

Abstract: High-Current Pulsed Electron Beam (HCPEB) was employed for the surface irradiation of solid solution Mg-Gd-Y-Nd alloy. The microstructures of the specimens before and after the irradiation were characterized in detail using X-Ray Diffraction (XRD), Optimal Microscopy (OM) and Scanning Electron Microscopy (SEM). The microhardness and corrosion resistance of the irradiated samples were also examined. The experiment results indicate that the sample surface was remelted after HCPEB irradiation. The electrochemical corrosion resistance of the irradiated surfaces was improved obviously. Grain refinement on the surface, the formation of remelting layer and the solid solution strengthening effect of rare earth elements are believed to be the dominating reasons for the improvement of the hardness and corrosion resistance performance.

Key words: metallic materials, high-current pulsed electron beam (HCPEB), Mg-Gd-Y-Nd alloy, surface microstructure, microhardness, corrosion resistance
