スッパタリング用ターゲットに用いられたりしている。For example, graphite alone is used as a structural material for nuclear fuel reactors due to its excellent thermal shock resistance at high temperatures, and due to its high thermal conductivity and good lubricity,
It is used in casting molds and sleeves, in hot press molds due to its excellent high-temperature strength, and in sputtering targets due to its high conductivity.

イス材、及びピストンヘッドに用いられている。As carbides, for example, titanium carbide is used as a main component of hard heat-resistant alloys such as cermets due to its excellent high-temperature strength, silicon carbide is used for heat exchanger partition walls, and tungsten carbide is used for its corrosion resistance.

It is also used as a.
この様に、炭素材料の用途は、広範に、かつ着実に、拡
大しつつ有るが、実際に工業化を進めるには、なお問題
点を残している。As described above, the uses of carbon materials are widely and steadily expanding, but problems still remain in order to actually advance industrialization.
一般に、工業装置の大型化、高機能化の要求は、日増し

しも容易ではない。更に、複雑な形状をした鋳造モール
ドなど、いわゆるニア・シェーブで作り上げるにも、そ
の加工成形には、制約がある。In general, demands for larger and more sophisticated industrial equipment are increasing day by day, and it is not always easy to create each component as a single piece due to restrictions due to the nature of the manufacturing equipment or the functions of each material. . Furthermore, even when creating a casting mold with a complex shape using a so-called near shave, there are restrictions on the processing and shaping.

の金属配管との組み合わせ、特に熱伝導性を高めるため
接合が必要である。In addition, even if the properties of carbon materials are fully utilized, there are many cases in which even higher properties are required. For example, in nuclear fuel reactor structural materials, the thermal load placed on graphite as a structural material is large, and forced Water cooling may be required, but water cooling of the graphite material itself is impossible due to its water permeability, and it is necessary to combine it with metal piping for water cooling, especially bonding to improve thermal conductivity.

In many cases, it is sufficient to use only the back layer, and the base layer below (above) the front (back) layer may be made of a material different from that of the front (back) layer.
このような要求に対する最も普通の手段は炭素材と他の

This connection provides each of the above functions and is a means for dealing with complex functions.
このような要請からこの種上記材料同志の接合について

充分であったり、或いは接合材により制約があったり、
或いは操作に煩雑な手間や時間を要したりするものが多
く、現在なお満足すべき方法は極めて少ない。However, all of the various conventional bonding methods have insufficient bonding strength, or have limitations due to the bonding material.
Alternatively, there are many methods that require complicated operations and time, and there are currently very few methods that are satisfactory.

炭素鋼、各種合金鋼等が好ましい例として例示出来る。In the present invention, the materials to be joined are carbon materials or carbon materials and metal materials. However, this does not include the case where carbon steels are joined together, especially when carbon steels are joined together. The carbon material at this time is 0.2% by weight of free carbon, preferably 0.
It is a carbon material containing 65% by weight or more, and of course does not contain hydrated carbon or hydrocarbons. Here, the carbon material containing 0.2% by weight or more of free carbon means at least 0.22% of carbon that binds and diffuses with iron or iron alloy during heating.
&-1% or more. For example, WC, which is the basic component of cemented carbide, is stable even when heated for a long time below 12 (10'C), but contains about 0.4% of unstable (free) carbon, which contributes to bonding. The same applies to other carbides.In this case, if the free carbon content is less than 0.2% by weight, it will not create a bridging effect with the carbon material, which is undesirable.A specific example of this is graphite alone. Examples include those consisting of carbon alone, carbides of various metals, or composites with other materials containing at least one of these as a component, and various other ceramics and metals containing a predetermined amount of free carbon. Preferred examples of carbides of various metals include titanium carbide and silicone carbide, as well as carbon steel and various alloy steels.

ある。Further, the metal material to be joined includes a wide variety of metals, and metals also include alloys. Preferred metals include tungsten, molybdenum, iron, silicon, Hastelloy, carbon steel, various alloy steels such as stainless steel, and the like.

経済である。In the present invention, this bonding material is used in a state in which iron or iron alloys, particularly plate-like or thin-plate iron or iron alloys, are coated in advance. Alternatively, the graphite or metal material to be joined is coated with copper in advance. The coating method at this time is not limited in any way, and includes electrolytic plating, chemical plating, plating, chemical thermal vapor deposition,
Various methods such as precipitation method and metal spraying method based on ionization tendency are widely adopted. By coating in advance in this manner, handling during bonding becomes extremely easy. The coating thickness is usually 0.05 to 0.5M, preferably 0.05 to 0.2M.
It is about m. If it is too thin, unevenness may occur in the iron scrap,
If it is too thick, the bonding effect may actually decrease, and it is also uneconomical.

It is 5M or less. At this time, the thickness is less than 1M (if it is too thick, the impact resistance of the joint may deteriorate, so it is not very desirable).

ゴン、窒素ガス等を使用すれば良い。When carrying out the method of the present invention using these many materials,
As already explained with reference to FIG. 1, a thin plate or foil-like body (5) of iron or an iron alloy, preferably made of iron or iron alloy, is used as a core material and the bonding material (4) is coated above and below in advance. As the bonding conditions, either a vacuum, an inert gas atmosphere, or the presence of flux is used, or two or more of these methods are used in combination. This is to prevent the surface of the bonding material from being oxidized. In this case, under vacuum refers to a state where the amount of oxygen is so small that there is virtually no effect of oxygen, and usually 1
The pressure is less than 0-' atm, preferably about 10-' atm, and a normal inert gas such as argon or nitrogen gas may be used as the inert atmosphere.

When using this flux, it may be carried out in the air or in the above atmosphere. Note that the flux is volatilized by evaporation, decomposition, etc. under heated bonding conditions and does not remain on the bonding surface.
加熱条件としては原則的には接合材中に鉄合金が晶出し
うる温度であり、通常接合材の軟化点よりも高温好まし
くは５０°Ｃｉｉｌ後高温である。The heating conditions are, in principle, a temperature at which the iron alloy can crystallize in the bonding material, and is usually higher than the softening point of the bonding material, preferably at a temperature after 50°C.

れることは当然である。Materials bonded by the method of the present invention can be widely used in various fields by taking advantage of their excellent bonding strength. For example, a bonded product of graphite sheets, which is a bonded product of carbon materials, is effectively used as a packing material for high-temperature pipe joints, a valve seat for a high-temperature ball valve, a heat shielding material, a bearing, a gasket for automobiles, and the like. In addition, bonded products of carbon materials and metal materials are used more widely in various fields, such as bonded products of carbonaceous composite materials (hereinafter referred to as C7C materials) and metals.
Examples include a material in which a bolt or the like is joined to a C material, and a material in which a metal pipe is joined to one side of a C/C material. The former, which is made by joining bolts, etc., is the first part of the fusion plasma confinement device.
It is suitable for attaching the carbon material to the wall, and the one with pipes joined is also extremely excellent as a structural member to which water circulation pipes are connected for the purpose of cooling the parts that receive high load heat inside the plasma confinement device. In addition, it is also used in a form in which a cooling pipe is similarly joined to the back surface of the carbonaceous laser beam reflecting mirror. It goes without saying that the bonding method and bonded product of the present invention are not limited to the above-mentioned examples, and can be widely used in various other fields in which carbon materials have been conventionally used.
