Abstract
A highly heat-resistant laminated component for a fusion reactor has at least of a plasma-facing area made of tungsten or a tungsten alloy, a heat-dissipating area of copper or a copper alloy with a mean grain size of more than 100 μm, and an interlayer of a refractory metal-copper-composite. The refractory metal-copper-composite has a macroscopically uniform copper and refractory-metal concentration progression and a refractory metal concentration of between 10 vol. % and 40 vol. % over its entire thickness.
Claims26
A highly heat-resistant composite component for a fusion reactor, comprising:
- a plasma-facing area made of tungsten or a tungsten alloy with a tungsten concentration of >90% by weight, a heat-dissipating area of copper or a copper alloy with a thermal conductivity of >250 W/mK and a mean grain size of >100 μm, and an area in between said plasma-facing area and said heat-dissipating area of a refractory-metal-copper composite;
- said refractory-metal-copper composite having a macroscopically uniform copper and refractory metal concentration progression and a refractory metal concentration x of 60 vol. %<x<90 vol. % throughout a thickness d of 0.1 mm<d<4 mm, and a refractory metal phase forming a virtually continuous skeleton.
