Layers (gradient composition control layers) are arranged to continuously change physical properties such as thermal expansion and structure, and at the same time provide heat resistance with ceramics.
The metal provides thermal conductivity and mechanical strength. Furthermore, functionally graded materials not only have a thermal stress relaxation function, but also can be adapted to the required environment by controlling changes in characteristic values such as Young's modulus, coefficient of thermal expansion, thermal conductivity, and electrical conductivity as well as changes in composition. It can be made functional. In addition, as a functionally graded material, a homogeneous material whose structure has a graded function is also considered.

［実施例］
以下、この発明の実施例を図面に基づき詳細に説明する
。[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.
第１図はこの発明の材料の端部接合処理構造の一実施例
にかかり、傾斜′機能材料に適用した場合の概略構成図
である。FIG. 1 is a schematic diagram of an embodiment of the material end joining treatment structure of the present invention, when applied to a functionally gradient material.
この材料の端部接合処理構造１０では、接合対象となる
材料１１が傾斜機能材料であり、これまで考えられてい
る傾斜機能材料は、例えば表面１１ａがセラミックス１
２とされ、裏面１１ｂが金属１３となっており、これら
の中間層は、組成が表裏方向（厚さ方向）の−次元的に
連続して変化するようになっている。In this material edge joining structure 10, the material 11 to be joined is a functionally gradient material, and in the functionally gradient material that has been considered so far, for example, the surface 11a is made of ceramic material.
2, and the back surface 11b is made of metal 13, and the composition of these intermediate layers changes continuously in the -dimensional direction in the front and back directions (thickness direction).
このため材料１１の裏面１１ｂは金属１３であることか
ら構造材などの金属と簡単に溶接を行なって接合するこ
とができるが、材料１１の端部１１ｃでは、裏面１１ｂ
付近が金属１３であることから溶接ができるとしても端
部１１ｃ全体を接合することができない。Therefore, since the back surface 11b of the material 11 is the metal 13, it can be easily joined to a metal such as a structural material by welding, but at the end portion 11c of the material 11, the back surface 11b
Since the vicinity is made of metal 13, even if welding is possible, the entire end portion 11c cannot be joined.
そこで、この材料１１の端部接合処理構造１０では、接
合端部方向、すなわち材料１１の幅方向Ｘ及び長さ方向
Ｙについても組成を中央部から端部１１Ｃに向かって連
続的に最外端部が金属１３となるように傾斜化している
。Therefore, in the edge joint treatment structure 10 of the material 11, the composition is continuously changed from the center toward the end 11C in the direction of the joint ends, that is, in the width direction X and the length direction Y of the material 11. It is sloped so that the part becomes metal 13.
したがって、この材料１１ては、板厚方向の組成の傾斜
化とともに、表裏面と平行な面方向にも組成が傾斜化さ
れ、二次元的に組成が傾斜化されている。Therefore, in this material 11, the composition is graded not only in the thickness direction but also in the plane direction parallel to the front and back surfaces, so that the composition is two-dimensionally graded.
このため材料１１の端部は金属１３が１００９６となっ
ているので、金属の構造材やこの材料１１同志で端部１
１Ｃの溶接による接合ができる。Therefore, since the metal 13 is 10096 at the end of the material 11, the end 1
Can be joined by 1C welding.
次に、第２図に示す材料の端部接合処理構造２０では、
接合対象となる材料２１を均一組成のセラミックス２２

The material 21 to be bonded is a ceramic 22 with a uniform composition.
This is the case.
このようなセラミックス２２だけの材料２１の端部２１
ａを溶接によって接合できるようにするため、接合端部
方向にセラミックス２２と金属２３とで組成を連続的に
変化させて傾斜化し、最外端部が金属２３となるように
しである。The end portion 21 of the material 21 made of only such ceramics 22
In order to be able to join a by welding, the composition of the ceramic 22 and the metal 23 is continuously changed in the direction of the joining end so that the composition is graded so that the outermost end is the metal 23.
すなわち、この材料２１では、端部方向、長さ方向Ｘに
ついてのみ一次元的に組成が傾斜化されている。That is, in this material 21, the composition is one-dimensionally graded only in the end direction and length direction X.
このため材料２１の端部２１ａは金属２３が１００％と
なっているので、金属の構造材やこの材料２１同士で端
部２１ａの溶接による接合ができる。Therefore, since the end portion 21a of the material 21 is made up of 100% metal 23, it is possible to join the end portions 21a of the metal structural members or the materials 21 together by welding.
次に、このように材料１１．２１の接合端部を金属１０
０％の組成となるように処理する材料の端部接合処理方
法の一実施例について、第３図に示す工程にしたがって
説明する。Next, connect the joint end of the material 11.21 to the metal 10 in this way.
An example of a method for processing the edge joining of materials to have a composition of 0% will be described according to the steps shown in FIG.

の充填に際しては、金型３６がＸ−Ｙ方向に移動され、
金型３６の各部が所定の２次元的に連続する組成変化と
なるように傾斜化する。The composition ratio of the two raw material powders 31 and 32 and the binder 33 is adjusted by the composition ratio adjustment valve 34, mixed by the mixing nozzle 35, and then injected into the mold 36. Raw material powder 31.32 from this mixing nozzle 35 to the mold 36
When filling, the mold 36 is moved in the X-Y direction,
Each part of the mold 36 is sloped so that the composition changes in a predetermined two-dimensional manner.
こうして金型３６に原料粉末３１．３２が充填去れた後
、所定の形状に加圧成形される。After the raw material powders 31 and 32 are filled into the mold 36 in this way, they are press-molded into a predetermined shape.
最後に、加熱焼結が行われ、傾斜材料が完成する。この

度に保持することができる。Finally, heating and sintering is performed to complete the gradient material. For this heating and sintering, a device that combines a sintering furnace for uniform heating and a laser heating device is used to heat the raw powder with a temperature gradient added to it in accordance with the gradient of the composition of the raw material powder. By doing so, the sintering temperature of each composition can be maintained.
したがって、傾斜機能材料であっても噴射充填法（混合

士や金属の構造材などと既存の溶接法で接合することが
できる。Therefore, even for functionally graded materials, it is possible to join them by combining the injection filling method (filling raw material powder with a mixing nozzle) and the gradient heating method (heating with a sintering furnace for uniform heating and a laser heating device). Two-dimensionally sloped materials with metal ends can be easily created, and these materials can be joined to each other or to metal structural materials using existing welding methods.
次に、このような材料の端部接合処理が行われた耐熱用

できる。When this functionally graded material 41 is bonded to a metal structural member 45 via the plate fins 44, the bonding with the plate fins 44 is performed on the back surface 41b of the functionally graded material 41.
This can be done using the metal 43 part, and can be joined using existing brazing or diffusion bonding methods. Furthermore, functionally graded material 4
Since the outermost end of the joining end portion 41c of No. 1 is made of metal 43, it can be easily joined to the structural member 46 using existing welding methods such as laser welding or electron beam welding.
