The Manufacture of Carbon Armoured Plasma-Facing Components for Fusion Devices

摘要

Within the last decade Plansee has been active in the development and manufacture of different Plasma-Facing-Components for nuelear fusion experiments consisting in a tungsten or CFC-armour joined onto metallic substrates like TZM, stainless steel or copper-alloys. The manufacture of these components requires unique joining technologies in order to obtain reliable thermo mechanical stable joints able to withstand highest heat fluxes 晈ithout any deterioration of the joint. In an overview the different techniques will be presented by some examples of components already manufactured and successfully tested under high heat flux conditions. Furthermore an overview will be given on the manufacture of different high heat flux components for TORE SUPRA, Wendelstein 7-X and ITER.
