Composite component for fusion reactors

A method for producing a highly heat-resistant laminated flat tile component, which comprises:

• bonding one or more shaped parts of tungsten or tungsten alloy with one or more plate-shaped parts of a refractory metal-copper-composite in vacuum or a non-oxidative gas atmosphere;
• joining the shaped parts to an area made of copper or a copper alloy by melting the copper-containing constituents and subsequently cooling to room temperature;
• mechanically processing the resulting component;
• and
• subsequently bonding the mechanically processed component in a form-fit with a metal component having a strength of >300 MPa in a bonding process selected from the group consisting of welding, soldering, brazing, diffusion, and a plating process.

A method for producing a highly heat-resistant monoblock component, which comprises:

• bonding one or more shaped parts of tungsten or a tungsten alloy and formed with bores to one or more ring-shaped parts of a refractory metal copper-composite in a vacuum or inert gas atmosphere;
• bonding to an area consisting of copper or a copper alloy by melting the copper-containing constituents and subsequently cooling to room temperature;
• mechanically processing the resulting component;
• subsequently bonding the mechanically processed component in a form-fit with a metal component having a strength of >300 MPa in a bonding process selected from the group consisting of welding, soldering, brazing, diffusion, and a plating process.
