| 摘 要： | Carbon-base materials is one of candidate plasma facing materials and have been widely used in current tokamak facilities in the world. But some defect properties are presented on high yield of chemical sputtering, high yield of radiation enhancement sublimate (RES), cracking after heat flux in divertor and so on. These characteris are related to the interstitial carbon atom producing and mobile, so it can be improved by doped some little other elements into the carbon-base materials, such as boron, silicon, titanium and so on.
