Abstract

Surface engineering of UMo particles, i.e. the coating of UMo powder with diffusion limiting elements using DC magnetron sputtering, has been suggested as a remedy to excessive UMo/Al interdiffusion. Samples from full size plates produced with UMo powder coated with Si (300nm and 600nm) and ZrN have been examined before and after irradiation with Iodine at 80MeV. In case of Si coated UMo particles, a dense Si rich layer developed around the UMo particles during plate fabrication. In contrast, the ZrN layer frequently revealed cracks. During heavy ion irradiation, no UMo/Al interdiffusion occurred at spots that are protected by a sufficiently thick Si rich layer layer or a dense ZrN layer. In contrast, a conventional UMo/Al interdiffusion layer (IDL) occurred at spots where the UMo has not been protected by a Si rich layer layer or the ZrN layer was broken.
