このため、例えば、ろう付け方法においては、
白金系に代るろう材としてジルコニウム（Zr）
が試みられた。 For this reason, for example, in the brazing method,
Zirconium (Zr) as a brazing material instead of platinum
was attempted.
このZrは、たしかに、白金系ろう材に比べて
安価ではあるが、しかし、ろう付け時におけるＣ

しも充分でなかつた。 This Zr is certainly cheaper than platinum-based brazing filler metal, but it
The effect of suppressing the diffusion of C from the member to the W member or the Mo member was weak, and the strength after joining was not necessarily sufficient.

The present inventors conducted a search for a brazing filler metal that is effective in achieving the above object, and found that an alloy of zirconium (Zr) and tungsten (W) or molybdenum (Mo), which will be described later, is useful. This finding led us to develop the present invention.

83重量％、ＷもしくはMoが17〜19重量％である
ことが好ましい。得られるものはＣ拡散抑制機能
も優れている。 In the alloy of Zr and W or Mo used in the present invention, taking the Zr and W alloy as an example, if the composition ratio of Zr is too small, the brazed part will be brittle.
ZrW 2 phase may precipitate and cause problems such as impairing the integrity of the brazed area, and if it becomes too large, the fluidity of the brazing metal may deteriorate and the brazed area may become uneven. This may cause problems. Therefore, the composition of the alloy needs to be within a limited range of 80 to 85% by weight of Zr, 15 to 20% by weight of W or Mo, and 81 to 85% of Zr.
Preferably, the content is 83% by weight, and 17-19% by weight of W or Mo. The obtained product also has an excellent C diffusion suppressing function.
ZrとＷもしくはMoとの合金は箔状、線状、粉
末状いずれの形体でも使用できるが、Ｗ部材もし
くはMo部材とＣ部材との密着性を高めるという
点では箔状の形体が好ましい。 The alloy of Zr and W or Mo can be used in any form of foil, line, or powder, but a foil form is preferable in terms of improving the adhesion between the W member or Mo member and the C member.

あまり薄いと接合効果が低下するので、通常は30
〜50μｍ更に35〜45μｍ程度に設定される。 In the present invention, first, the alloy of Zr and W or Mo is placed on the joint surface of the C member, and then other members are placed on top of this. If the thickness of the alloy layer is too thick, cracks are likely to occur between each layer due to thermal distortion due to the difference in thermal expansion between the layer and the component during cooling after brazing, and if it is too thin, The bonding effect decreases, so it is usually 30
~50 μm and further set to about 35 to 45 μm.

×10 -3 ~1×10 -6 Torr and even 1×10 -4 ~1×
Approximately 10 -5 Torr is good. In addition, the heating temperature must be higher than the melting point of the brazing material, but if it is too high, the corrosion of the brazing material on the W member or the Mo member becomes noticeable and the brazed part becomes brittle. In this case, the temperature is set in the range of 1600 to 1650°C.

They are integrally joined via an alloy layer of Zr and W or Mo. In addition, the whole may be hot-pressed during this heat treatment.
