摘　　要：本文介绍了一种强流脉冲电子束材料表面改性装置 ,并对其基本构造及工作原理进行了剖析。电子束产生部分由爆炸电子发射阴极、等离子体阳极及导向磁场构成。在对该装置测试的基础之上 ,我们采用不同的工艺参数进行了 Al材表面改性实验。分析及测试结果表明 。High current pulsed electron beam (HCPEB) was developed for surface modification of materials in recent years. In this paper, a new equipment using HCPEB is introduced. The mechanism to produce HCPEB was discussed in detail. The electron gun can be divided into explosive electron emission (EEE), anode plasma (AP) and oriented magnetic field. After testing of this machine, experiments, with different working parameters, were carried out on aluminum samples. Results of analysis and testing show that the microstructure of surface layer changed intensively.
