SOME PROBLEMS OF PLASMA-MATERIAL INTERACTIONS IN FUSION DEVICESGennady P. Glazunov1, Evgeny D. Volkov1, Vladymir I. Lapshin1, Vladymir I. Tereshin1, Marek Sadowski2, Jerzy Langner2, Jacek Stanisławski2 1 Institute of Plasma Physics, National Scientific Center KhIPT, 310108 Kharkov, Ukraine 2 The Andrzej Soltan Institute for Nuclear Studies, 05-400 Otwock-Swierk, Poland The paper concerns some questions connected with the interaction of high-temperature plasma-ion fluxes with solid materials inside experimental chambers used for fusion-oriented research, and particularly inside the Torsatron-type facilities. Mechanisms of the boron carbide erosion are described and discussed. Also described is the behaviour of TiN-coated stainless-steel surfaces under the irradiation with hydrogen plasma-ion fluxes. In summary, there are described damages in the boron carbide layers and changes in the composition of the TiN-coatings. Close X |
