Abstract：
Effect of doping method of ThO2 on the microstructure and mechanical properties of Th-W cathode carbonized were studied by solid - solid and liquid-solid doping ways. The microstructure of Th-W cathode carbonized was analyzed by SEM,EDS and microscope, and mechanical properties of Th-W cathode carbonized were measured by static pressure gauge and impact tester. The results show that uniformity of ThO2 by liquid-solid doping is better than by solid-solid doping, and the grain size of Th-W cathode carbonized by liquid-solid doping is significantly smaller, compared with the grain size by solid-solid doping. Static strength and anti-impact energy of Th-W cathode are higher than Th-W cathode by solid-solid doping. © 2016, University of Science and Technology Beijing. All right reserved.
