Qualification of Tungsten Coatings on Plasma-Facing Components for JET

This contribution summarised the work that has been performed to establish the industrial production of tungsten coatings on CFC for application within the ITER-like Wall Project at JET. This comprises the investigation of vacuum plasma-sprayed coatings, physical vapour deposition tungsten/rhenium multilayers, as well as coatings deposited by combined magnetron-sputtering and ion implantation. A variety of analysis tools were applied to investigate failures and oxide and carbide formation in theses systems.
