Specialists from the Efremov Institute of Electrophysical Apparatus (part of Rosatom State Corporation), in collaboration with NUST MISIS, have developed a material for manufacturing divertor elements for a tokamak with reactor technologies (TRT), which is planned to be built in Troitsk. This was reported by the state corporation's press service.
Tungsten, due to its high thermal conductivity and melting point, as well as low rate of ion and thermal erosion, is the most suitable material for the protective lining of plasma-facing elements, but it is not suitable for creating a heat-dissipating base due to its high brittleness and poor compatibility with other metals.
To solve the problem, scientists plan to mix a porous tungsten matrix with copper using vacuum infiltration. This matrix will be grown on a substrate of monolithic tungsten.
This approach allows synthesizing parts from metal powder layer by layer. This makes it possible to control their properties depending on the specific tasks.
Earlier www1.ru reported that Rosatom налаживает production of titanium powders for 3D printing.
