摘要/Abstract

摘要： 与传统基于热阴极电子枪的熔丝增材制造技术相比,基于丝束同轴冷阴极电子枪的熔丝增材制造技术具有明显优势。为了缩短与世界先进电子束熔丝增材制造技术的差距,通过分析丝束同轴冷阴极电子束产生机理,采用模拟仿真技术优化影响束流品质的阴极、阳极参数,根据仿真结果研制了一套具有完全自主知识产权的丝束同轴冷阴极电子枪。所研制的丝束同轴冷阴极电子枪输出束流呈现“X”形状,熔滴过渡模式可以调控,熔丝成形效率达到5.02kg/h。

Abstract: Compared with the traditional fuse additive manufacturing technology based on hot cathode electron beam gun, the fuse additive manufacturing technology based on gas discharge electron beam gun of beam coaxial wire has obvious advantages. In order to shorten the technology gap between the advanced fuse additive manufacturing technology of electron beam in the world, a set of gas discharge electron beam gun of beam coaxial wire with independent intellectual property rights has been developed by analyzing the generation mechanism of gas discharge electron beam gun, and optimizing the cathode and anode parameters that affect the beam quality by using simulation technology. The output electron beam of the gas discharge electron beam gun of beam coaxial wire presents an “X” shape, the droplet transfer mode can be adjusted, and the forming efficiency of the fuse additive manufacturing can reach 5.02kg/h.

Key words: electron beam coaxial wire, fuse additive manufacturing, electron beam, EB gun
