Abstract Tungsten “Metal wall” experiments are planned at JT-60SA to contribute to ITER. Because tungsten coated CFC materials are attractive for the “metal wall” experiments, their fabrication techniques need to be developed. Aiming to the application of divertor, a sinter bonding method is being developed to join thick tungsten plates and CFC blocks. Present research reports about the fabrication of W/CFC joints, basic microstructural and mechanical characterizations, and results of preliminary high temperature exposure tests at 1073 K and 1173K for 1000 h in medium vacuum.

JT-60SA 金属壁实验中钨涂层 CFC 板的微观结构稳定性

摘要 JT-60SA 计划进行钨“金属壁”实验，以促进 ITER。由于钨涂层 CFC 材料对“金属壁”实验很有吸引力，因此需要开发它们的制造技术。针对偏滤器的应用，正在开发一种烧结粘合方法来连接厚钨板和CFC块。目前关于 W/CFC 接头制造、基本微观结构和机械特征的研究报告，以及在 1073 K 和 1173K 下在中等真空中 1000 小时的初步高温暴露试验结果。
