摘要：

The behavior of thick B4C coatings on different graphites under high power electron beam irradiation, pulsed plasma irradiation and under DIII-D divertor plasma action was investigated. SiC-B4C coating on graphites produced in General Atomics and pyrolytic boron nitride were also tested in the plasma gun device. In the following tests at these facilities, the samples were examined using SIMS, EDAX, X-ray crystallography, profilometry and Auger spectroscopy. B4C coatings showed excellent durability under high heat flux irradiation and in conditions of real tokamak divertor plasma. The obtained results indicated that the use of RGT graphite (the graphite with high thermal conductivity) improves the durability of the B4C coating significantly. Pyrolytic boron nitride showed very small removal of the matter and no mechanical damage.
