Advances in vacuum arc cathode spots
真空电弧阴极斑点的研究进展
2.
By using a Scanning Electron Microscope (SEM), the tracks of cathode spots on the surface of nanocrystalline Cu cathode produced after the first discharge with peak current of 10 A was investigated.
采用扫描电子显微镜(SEM)观察了纳米Cu阴极在峰值电流为10A的小击穿电流下首击穿后的阴极表面烧蚀形貌,发现纳米Cu的阴极斑点从产生到熄灭期间的运动(即短程运动)并不是随机的,而是有一定取向的;进一步通过和常规Cu首击穿烧蚀形貌对比,分析了产生有向运动的原因。
