Based on the in situ diagnostic system and the digital image post-processing technique, quantifications of the anodic erosion components and heat transfer efficiency for tungsten and the W 80 Ag 20 material in arcs of argon, helium, and nitrogen were achieved. The leading vaporization of silver has been found to result in evidently lower anodic heat transfer efficiency and much smaller molten pools compared with those of the tungsten anode, but the intensive generation of silver vapor under the melt layer causes higher splashing erosion of the W 80 Ag 20 anode. However, these characteristics can be strongly changed by the cathodic blowing, which leads to a much higher splashing erosion of tungsten anode but a lower erosion rate of W 80 Ag 20 anode. Through the visualization of the erosion behavior and the post microanalysis of the anode surface, the possible driving mechanisms for the generation of the splashing dro...

W和W 80 Ag 20在大气压电弧中阳极腐蚀成分的演化和传热效率

基于原位诊断系统和数字图像后处理技术，实现了对钨和W 80 Ag 20材料在氩，氦和氮弧中的阳极腐蚀成分和传热效率的量化。已经发现，与钨阳极相比，银的主要蒸发会导致阳极传热效率明显降低，并且熔池要小得多，但是在熔体层下大量产生银蒸汽会导致W 80 Ag的更高飞溅腐蚀20个阳极。但是，这些特性可以通过阴极吹气而发生很大变化，从而导致钨阳极的飞溅腐蚀更高，而W 80 Ag 20阳极的腐蚀速率更低。通过腐蚀行为的可视化和阳极表面的后期微观分析，
