The surface quality of metal material directly affects its service life. In this paper, continuous scanning electron beam process (CSEBP) is used to treat the surface of 65 steel. The effects of electron beam current and moving speed on surface roughness are discussed. The results showed that: the surface roughness increased with increasing the bean current and the moving speed. When the electron beam current was 5 mA and the moving speed was 3 mm/s, the surface roughness of 65 steel decreased from 2$.0\mu$ m to 0.432$\mu$ m. Craters are mostly composed of carbon and oxygen compounds, which are easily ejected when the melt flow rate changes rapidly.

65钢的扫描电子束抛光及缺陷分析

金属材料的表面质量直接影响其使用寿命。在本文中，连续扫描电子束工艺（CSEBP）用于处理65钢的表面。讨论了电子束电流和移动速度对表面粗糙度的影响。结果表明：表面粗糙度随着豆电流和运动速度的增加而增加。当电子束电流为5 mA且移动速度为3 mm / s时，65钢的表面粗糙度从2$。0\mu$ m至0.432$\mu$ 米 弹坑主要由碳和氧化合物组成，当熔体流量快速变化时，碳和氧化合物很容易喷出。
