| 内容記述 | In National Institute for Fusion Science (NIFS), dissimilar material bonding technique using Spark Plasma Sintering (SPS) method has been developed to join the high heat load armor to the heat sink in target plates of the divertor component in fusion experimental devices. Tungsten (W) which is the first candidate of the divertor armor material in fusion reactors has been tried to bond to various heat sink materials, i.e., copper ally (CuCrZr), molybdenum alloy (TZM), stainless steel (SS), graphite or carbon fiber reinforced composite (C/CFC). Up to now, the W-CuCrZr bonded divertor tile for LHD succeeded in the heat load test with e-beam of 23 MW/m2, quasi steady-state (10 minutes) and of 15 MW/m2, 10 sec, 100 times cyclic (duty cycle = 50 %). In order to evaluate the bonding performance, diagnostics with SEM/EDS on the bonding surface, together with the shear stress test were performed. In the paper, recent progress of research and development for dissimilar material bonding with SPS are overviewed. | |||||||||||||||||||||||
