Functionally graded components are usually preferred for severe and critical service conditions, thanks to the possibility of achieving different complementary material properties within same structure. Wire + Arc Additive Manufacturing is an emerging technology which lends itself well production sound structures. In this study, integral structure two functional gradients, namely tantalum molybdenum, molybdenum tungsten, was successfully deposited. A linear gradient observed in both...

Abstract In the conceptual design of EU-DEMO, damage to plasma-facing components under disruption events is planned be mitigated by specific sacrificial limiter components. A new concept has been proposed using lattice structures fabricated with tungsten powder additive manufacturing techniques. The major potential benefits a structure for limiters are possibility customise thermal conductivity and structural compliance these manage temperatures stress within material limits lower...

Tungsten is the leading candidate to provide a critical protective coating for copper and steel-based plasma facing components in nuclear reactors. However, fabrication of thick tungsten coatings on or steel challenged by significant difference melting points thermal expansion coefficients materials, which leads severe mismatch strains during manufacture service. This challenge investigated using new processing approach — field assisted sintering nanopowders directly onto pre-sculptured...
