“…The CODMAT rig allows irradiating materials with high-density ion or electron fluxes and depositing coatings (Airapetov et al [5]). The experiments were conducted with 15×7×1 mm tungsten substrates rinsed in an ultrasonic ethanol bath and then irradiated by argon ions before the deposition to provide proper coating adhesion.…”

“…The results of these topics' investigations are the subject of this presentation. The paper considers the results of ion irradiation and thermal cycling of boron carbide coating on tungsten sample in Stand for Coating Deposition and Material Testing, CODMATT (National Research Nuclear University (MEPhI)) [7], and plasma irradiation during a plasma disruption in fusion device (T-10 tokamak, National Research Center "Kurchatov Institute," Moscow).…”

The application of the in situ renewable protecting boron carbide (B 4 C) coating can prevent plasma-facing materials of plasma technology and thermonuclear devices from plasma irradiation and by this means prevents their destruction and plasma contamination by materials of their erosion. At the same time, the regimes and conditions of high adhesive deposition of B 4 C on tungsten and the B 4 C coating ability to withstand the thermal cycling and high-power density irradiation by plasma ions have not been investigated yet. The chapter considers the results of ion irradiation and thermal cycling of boron carbide coating on tungsten sample in Stand for Coating Deposition and Material Testing-CODMATT (NRNU MEPhI) and plasma irradiation during a plasma disruption in fusion device-T-10 tokamak (NRC "Kurchatov Institute"). Boron carbide coating withstands the thermal cycling and high-power density irradiation by plasma ions. It retains uniformity and adhesion to tungsten and protects it from direct plasma interaction for temperatures up to melting point of tungsten. The retaining of uniform coating in contact with tungsten substrate allows renewing the coating on its surface even after high-energy plasma loads.
