【摘要】Low-Z materials,such as carbon-based materials and Be,are major plasma-facing material (PFM) for current,even in future fusion devices.In this paper,new type of multielement-doped carbon-based materials developed are presented along with experimental results of their properties,The results indicate a decrease in chemical sputtering yield by one order of magnitude.a decrease in both thermal shock resistance and radiation-enhanced sublimation,an evidently lower temperature desorption spectrum ,and combined properties of exposing to plasma.
