Tore Supra is involved in flat tile carbon armoured plasma-facing components (PFCs) since 1985. In 1997, a third generation of components, based on the original concept developed with Plansee Company, called active metal casting (AMC) has been launched. Since 1998, 660 elementary components for the toroidal pump limiter (TPL are in production. The route of the manufacture is rather complex and many controls were requested all along the fabrication to ensure a high reliability of the elements. One of the main controls is the final infra-red (IR) test allowing to determine the quality of the bonding between the carbon fibre composite (CFC) tiles and the heat sink made of copper-chromium-zirconium alloy (CuCrZr). Although results for the first batch of elements were as expected (less than 5% rejected at the final test), unexpected defects appeared with the following batches. Investigations into the fabrication processes underlined the importance of having a better heat treatment of the pieces in copper alloy (CuCrZr), however this was not sufficient to completely explain the observed defects.
