摘要：

As　an　important　alternative　for　ThO2-W　filament　cathode,　La　2O3　doped　Mo　filament　has　aroused　a　lot　of　interest　in　the　past　several　decades　[1].　Carburization,　a　key　technical　process　for　the　treatment　of　filament　cathode,　has　a　great　effect　on　the　emission　property　of　the　cathode.　In　this　paper,　the　carburization　method　and　the　carburization　mechanism　have　been　studied　in　order　to　obtain　the　carburized　La　2O3　doped　Mo　filament　cathode　which　could　provide　good　emission　property.　©　2010　IEEE.
