采用电刷镀工艺在40Cr钢上制备Cr层，然后采用强电流脉冲电子束辐照技术进行处理。研究了辐照前后样品的表面微观结构。结果表明，Cr表面由均匀分布的小结节单元组成，这些小结节单元由小于100nm的细小Cr颗粒组成。经过强电流脉冲电子束处理后，表面出现许多裂纹。主要原因可能是电子束处理过程中沿样品表面积累的准静态热应力。由于电子束加热，表面晶粒由Cr颗粒生长而成，其尺寸小于200nm。
Cr layer was fabricated on 40Cr steel by electric brush plating process and then treated by high current pulsed electron beam irradiation technique. Surface microstructures of specimens before and after the irradiation were investigated. Results show that Cr surface is composed of uniformly distributed small nodule units which are composed of fine Cr particles smaller than 100nm. After high current pulsed electron beam treatment, many cracks are found on surface. The main reason is possibly due to the quasi-static thermal stresses accumulated along the surface of the specimens during the electron beam treatment. The surface grain grow from Cr particles because of heating by electron beam, and their size is less than 200nm.
