TECHNIQUE FOR SURFACE MODIFICATION OF MATERIALS BY HIGH-CURRENT PULSED ELECTRON BEAM

摘要: 介绍了一种强流脉冲电子束(电子炮)材料表面改性技术。首先对电子炮的基本构造及工作原理进行了剖析。然后，使用该装置对Al材料进行了表面改性实验，发现材料近表面层的显微结构及力学性能均发生了明显的变化。最后给出了强流脉冲电子束铝材表面改性的温度场模拟结果。

Abstract: A new surface modification technique with high current pulsed electro n beam （HCPEB） is discussed.The working principle and structure of the HCPEB ins trument are analyzed.The experimental results obtained from Al samples are prese nted.The near-surface structure and properties are significantly changed.Fanall y,the experimental results by a temperature field simulation are given.
