摘要/Abstract

摘要： 利用强流脉冲电子束(HCPEB)表面处理技术在45#钢表层合金化铬元素以获得高性能的合金复合改性层。利用X射线衍射、金相显微镜、扫描电子显微镜、透射电子显微镜、维氏硬度计以及电化学分析仪对合金化层的显微组织及性能进行了分析。实验结果表明:经强流脉冲电子束轰击合金化后,45#钢表面形成了厚度范围为4~9 μm的合金化改性层,Cr元素在样品表层发生了固溶,并与C元素结合析出颗粒细小弥散的Cr₂₃C₆增强相;此外,处理表面的显微硬度得到了显著提高,同时其耐腐蚀性能也得到改善。

Abstract: The chromium element is alloyed on 45# steel by High-Current Pulse Electron Beam (HCPEB) with pre-coating to obtain high quality alloyed layers. The microstructure and properties of the alloying layer are studied by XRD, OM, SEM, TEM and multi-purpose microcomputer electrochemistry analyzer. Analysis results show that, the formation an alloyed layer with the depth of about 4~9 μm on the surface is observed. The solid solution and diffusion of Cr element occurs on the surface of the substrate. C atoms generated by the dissolution of the cementite combine with the chromium to form a small amount of nano-grained carbide Cr₂₃C₆. The surface micro-hardness and the corrosion resistance of 20 steel after HCPEB alloying are remarkably improved compared with the original sample.

Key words: metallic material, high current pulsed electron beam(HCPEB), surface alloyed by electronic beam, micro-hardness, corrosion resistance
