摘要

A new approach for fabricating B_4C/Cu graded composite by rapid self-resistance sintering under ultra-high pressure was presented, by which a near dense B_4C/Cu graded composite with a compositional spectrum of 0-100% was successfully fabricated. Plasma relevant performances of sintered B_4C/Cu composite were preliminarily characterized, it is found that its chemical sputtering yield is 70% lower than that of SMF800 nuclear graphite under 2.7keV D~+ irradiation, and almost no damages after 66 shots of in situ plasma discharge in HL-1 Tokamak facility, which indicates B_4C/Cu plasma facing component has a good physical and chemical sputtering resistance performance compared with nuclear graphite.
