Abstract

This study discusses the qualification and application of two NDE techniques (ultrasonic and thermogravimetric analysis) for inspection of CFC-to-metal joints. Emphasis is directed to the annular geometry typical of macroblock/monoblock solutions for divertor high-heat-flux components. The development is focused specifically on the joint between carbon-fiber composite and TZM molybdenum alloy. The comparative results of the NDE inspections are discussed on the basis of the destructive examination of the samples. The nature and size of relevant and detectable defects are highlighted together with hints for a possible NDE strategy for divertor high-heat-flux components.
