Description
Technical Field
The invention relates to a tungsten copper sheet component with a tungsten fiber net reinforced copper-based composite layer for a fusion reactor, a manufacturing device and a manufacturing method thereof.
Background
The controllable nuclear fusion energy is an important research direction for future energy development, a divertor is a core component for controlling fusion reactor energy flow, particle flow, impurities and helium ash, a plasma-oriented component is a component directly interacting with plasma in a divertor area, and an extreme heat flow environment (surface heat load and neutron heat load) of the divertor requires that materials have high thermal conductivity and high mechanical strength, so that creep-resistant materials suitable for high-temperature environments are urgently needed to be developed. At present, aiming at a region with lower thermal load, a flat plasma-facing component is a feasible and low-cost solution, and the method mainly comprises the steps of introducing a circulating coolant into a high-strength high-thermal-conductivity copper-based (such as a precipitation-strengthened CuCrZr alloy) plate-shaped heat sink to realize high-efficiency heat dissipation by combining a tungsten component with the high-strength high-thermal-conductivity copper-based (such as the precipitation-strengthened CuCrZr alloy) plate-shaped heat sink, and often adding an intermediate transition layer (usually oxygen-free copper) between the tungsten component and the copper heat sink to release thermal stress slowly in order to relieve the problem of interface cracking caused by the mismatch of thermal expansion coefficients of the tungsten component and the copper heat sink. Therefore, the main structures of the current flat-plate type plasma-facing component are a tungsten plasma-facing material, a pure copper intermediate layer, a copper alloy heat sink and the like. The pure copper interlayer has high thermal conductivity, but is easy to generate high-temperature creep, namely plastic deformation and even fracture when being used in a fusion reactor high-temperature environment for a long time.
In order to enhance the high-temperature mechanical property of the pure copper intermediate layer, research at present proposes solutions for enhancing copper-based composite materials such as tungsten particles, tungsten fibers, SiC particles, SiC fibers and the like, wherein the thermal conductivity of a SiC reinforcement body is quite low, which leads to the reduction of the overall heat transfer property of the composite material. Tungsten fibers have excellent tensile strength (ultimate tensile strength of up to 2.3-2.5GPa), excellent bending flexibility and ductility, and higher levels than other types of high strength fibers. In addition, the tungsten fiber has relatively high thermal conductivity, excellent wettability and insolubility in copper, and the melting points of tungsten and copper are obviously different, so that the method is favorable for adopting a liquid copper melt infiltration mode to manufacture the tungsten fiber reinforced copper-based composite material with remarkably improved high-temperature mechanical property and guaranteed thermal conductivity.
At present, the design of the tungsten fiber reinforced flat plate type copper intermediate layer mostly adopts the parallel arrangement of a single tungsten fiber along the flowing direction of a coolant, and the arrangement structure has randomness and only has a one-dimensional reinforcing effect due to the fact that the tungsten fiber is small in diameter and is not easy to place according to the size rule, so that the overall high-temperature mechanical property of the composite material still needs to be improved.

Further, the tungsten fiber net is formed by weaving tungsten fibers with the same diameter or by combining and weaving tungsten fibers with different diameters, so that tungsten fiber nets with different thicknesses are obtained; aiming at the aperture of the tungsten fiber net, namely the distance between the tungsten fibers in the adjacent parallel directions, the tungsten fiber nets with different apertures are woven according to the requirement, and the mesh number of the tungsten fiber net can be controlled.
Furthermore, the weaving angle of the tungsten fibers of the tungsten fiber net is vertical to each other or the tungsten fibers are woven in a cross inclined angle.
Further, the tungsten fiber net weaving structure is one of plain weave/twill weave/satin weave.
Furthermore, the high-melting-point metal sheet with the slotted hole is a stainless steel sheet or a molybdenum sheet; the thickness of the pure copper solidified and formed in the composite material is controlled by adjusting the thickness of the high-melting-point metal sheet with the slotted hole, namely the volume fraction of the oxygen-free copper serving as a matrix and the tungsten fiber net serving as a reinforcement in the composite material is easy to regulate and control.
Furthermore, in a tungsten copper sheet commonly used for a flat plasma-facing component, a tungsten fiber net in a two-dimensional plane direction is regularly placed, so that the mechanical property of a copper intermediate layer is enhanced in the two-dimensional direction, and the creep resistance of the tungsten fiber net reinforced copper-based composite material in a high-temperature environment is improved.

In order to obtain a flat plate type tungsten copper sheet commonly used facing a plasma body part, a tungsten sheet is placed on the lower portion of a tungsten fiber mesh in a tool, and a tungsten copper sheet component with a tungsten fiber mesh reinforced copper-based composite layer for a fusion reactor is prepared in one step by a liquid phase copper infiltration method.
As shown in fig. 1(a) -1 (c), according to an embodiment of the present invention, an apparatus for manufacturing a tungsten copper sheet member of a tungsten fiber mesh reinforced copper-based composite layer is provided, which includes a crucible cover 1, a crucible container 2, a smooth hole 3, oxygen-free copper 4, a stainless steel tool upper portion 5, a stainless steel tool lower portion 6, a tungsten sheet 7, a threaded hole 8, a tungsten fiber mesh 9, and a high melting point metal sheet 10 with a slotted hole.
Specifically, the preparation method comprises the following steps:

And finally, covering a crucible cover 1 on the crucible container 2, putting the tool into a heating furnace, and preparing the tungsten copper sheet component with the tungsten fiber mesh reinforced copper-based composite layer by using a liquid phase copper infiltration method.
As shown in fig. 2(a) -2 (b), the tungsten fiber net 9 is woven according to a regular size, and the high melting point metal sheets 10 and the tungsten fiber net 9 with the slotted holes are alternately arranged according to the designed interval size, so that the regular placement of the reinforcement tungsten fiber net 9 in the matrix is realized, and meanwhile, the thickness of the high melting point metal sheets 10 with the slotted holes can be set, namely, the volume fraction of pure copper is controlled, and the accuracy of structural design is improved; the enhancement in the one-dimensional direction of a single fiber is upgraded into the enhancement in the two-dimensional direction of the flaky tungsten fiber net, so that the enhancement effect on the copper intermediate layer is improved;
the weave of the tungsten fibre web 9 can be designed as desired. According to the diameter of the tungsten fiber, the tungsten fiber with the same diameter can be selected or the tungsten fibers with different diameters can be selected for combined weaving according to the requirement; aiming at the aperture of the tungsten fiber net 9, namely the distance between the tungsten fibers in the adjacent parallel directions, the tungsten fiber net 9 with different apertures can be woven according to the requirement, and the mesh number of the tungsten fiber net 9 can be controlled. Aiming at the weaving angle of the tungsten fibers, the tungsten fibers can be vertically woven or the tungsten fibers can be woven in a cross inclined angle according to the requirement. According to the weaving structure of the tungsten fiber net, plain weave, twill weave or satin weave can be carried out according to requirements.

The position of the slotted hole corresponds to a reserved hole on the upper part 5 of the stainless steel tool; meanwhile, the thickness of the pure copper solidified and formed in the composite material can be controlled by adjusting the thickness of the high-melting-point metal sheet 10 with the slotted hole, namely, the volume fractions of the pure copper (matrix) and the tungsten fiber (reinforcement) in the composite material are easily and accurately regulated and controlled. (according to the high/low demand of the heat load, namely the high/low demand of the heat exchange efficiency, in the area with high heat load, the volume fraction of the tungsten fiber is correspondingly increased for improving the creep resistance, and in the area with low heat load, the volume fraction of the tungsten fiber is correspondingly reduced for reducing the material cost when the creep resistance demand is lower.)
