For wear-resistant parts such as rolling rolls, the entire member is not made of wear-resistant material, but only the layer that requires wear resistance is made of wear-resistant material, and the other parts are made of materials with relatively high toughness. It is advantageous in terms of structure and cost to form a laminated structure made of two types of materials. However, in general, the wear-resistant layer 4
The material forming the (wear-resistant layer) contains a large amount of carbide or is an alloy steel material with a high alloy content, so there is a difference in thermal expansion coefficient between it and the tough layer (base material layer). It is normal for this to occur. For this reason, cracks due to differences in thermal expansion coefficients often occur during the manufacturing process or during actual use.

ている。 In order to solve this problem, it is already known that it is effective to form a three-layer structure between the wear-resistant layer and the base material layer by forming an intermediate layer having a coefficient of thermal expansion between the two. In addition, the manufacturing method includes a method in which a plate material is sandwiched as an intermediate layer material between the base material layer and the wear-resistant layer, and the contact surfaces of the three layers are fused together by applying pressure under heat. A method of applying powder to a specified thickness on the surface of a base material layer as an intermediate layer material, overlaying a wear-resistant layer on top of this, and applying pressure under heat to sinter the powder layer and fuse the interface of the three layers. etc. are being carried out.

However, the above manufacturing method is effective when the wear-resistant member has a simple shape such as a flat plate, but when the shape of the intermediate layer is complex, it is difficult to form the intermediate layer material. It is extremely difficult to process the material and to form a wear-resistant layer on the upper surface thereof, and it is not easy to form the intermediate layer or the wear-resistant material layer to have a uniform thickness.
本発明は上記問題点を解決することを目的とす
る。 The present invention aims to solve the above problems.

The method for manufacturing a wear-resistant member of the present invention is a method for manufacturing a wear-resistant member comprising a base material layer, a wear-resistant material layer, and an intermediate layer having a coefficient of thermal expansion intermediate between the two, the method comprising: Ni on the surface of the base material; The content is 25-36at%
After forming an intermediate layer by thermal spraying Fe-Ni alloy, a caning material is applied to define a space for forming a wear-resistant material layer on the surface of the intermediate layer, and a wear-resistant material is formed in the space. It is characterized by filling a homogeneous mixed powder of self-fusing alloy powder and ceramic powder, sealing the space filled with the mixed powder while deaerating it, and then performing hot isostatic pressure sintering. .
本発明は、中間層材を溶射法により基材表面に
吹き付けて中間層を形成することとしたので、基
材表面が凹凸または湾曲した複雑な形状であつて
も、その表面形状に則した均一な層厚の中間層が
形成される。 In the present invention, the intermediate layer is formed by spraying the intermediate layer material onto the surface of the base material using a thermal spraying method, so even if the surface of the base material has an uneven or curved complex shape, it can be uniformly formed according to the surface shape. An intermediate layer with an intermediate thickness is formed.
また、中間層材であるFi−Ni合金の熱膨張係

とも可能である。 In addition, as shown in Figure 4, the thermal expansion coefficient of the Fi-Ni alloy, which is the intermediate layer material, is as follows: Ni content: 25 to 36at
% range, it always changes over a wide range from 1 × 10 -6 to 16 × 10 -6 /℃, so by changing the Ni content, you can relatively freely change the temperature between the base material layer and the wear-resistant material layer. It is possible to form an intermediate layer having a coefficient of thermal expansion of . In the formation of that intermediate layer,
By using two or more types of Fe-Ni alloys with different Ni contents and sequentially spraying them onto the base material surface and stacking the sprayed layers, the coefficient of thermal expansion gradually changes from the base material layer side to the wear-resistant material layer side. It is also possible to form an intermediate layer that changes to

の耐摩耗材層は中間層を介して形成されるので、
基材層との熱膨張係数の差が大きい場合でも、比
較的厚い層厚に形成することができる。 Furthermore, the wear-resistant material layer formed using a mixed powder of a self-fusing alloy powder and a ceramic powder as a wear-resistant material is a sintered alloy having a composite structure consisting of a metal matrix and ceramic particles distributed as a dispersed phase in the matrix. Therefore, it has extremely high hardness and excellent wear resistance. In addition, since the wear-resistant material layer is formed through an intermediate layer,
Even when the difference in thermal expansion coefficient from the base material layer is large, the layer can be formed to have a relatively thick layer thickness.

触界面は十分に融着し強固な結合関係をなしてい
る。 In addition, in the present invention, the base material layer, intermediate layer, and wear-resistant material layer are integrally molded using a hot isostatic pressure sintering method, so each layer is dense and the contact interface between each layer is sufficiently They are fused and form a strong bonding relationship.
本発明の耐摩耗材料を構成する自溶性合金は、
Ni−Cr系（例えばCr：10〜17％、Fe、Ｂ、Si等
５％以下、残部Ni）あるいはCo系合金などであ
る。 The self-fluxing alloy constituting the wear-resistant material of the present invention is
It is a Ni-Cr alloy (for example, Cr: 10 to 17%, Fe, B, Si, etc. 5% or less, balance Ni) or a Co-based alloy.
自溶性合金粉末に配合されるセラミツク粉末
は、例えばタングステンカーバイド（WC）、チ
タンナイトライド（TiN）、チタンボライド
（TiB2）等の粉末である。 The ceramic powder blended into the self-fusing alloy powder is, for example, tungsten carbide (WC), titanium nitride (TiN), titanium boride (TiB 2 ), or the like powder.
自溶性合金粉末に対するセラミツク粉末の配合
量は目的とする耐摩耗部材の用途・使用条件等に
もよるが一般的に５〜80重量％の範囲が適当であ
る。５重量％未満では、セラミツク粒子の分散効
果が不足し、一方80重量％を越えると、耐摩耗材
層が脆弱となるからである。 The amount of ceramic powder to be blended with the self-fusing alloy powder depends on the intended use and conditions of use of the wear-resistant member, but is generally in the range of 5 to 80% by weight. If it is less than 5% by weight, the dispersion effect of the ceramic particles will be insufficient, while if it exceeds 80% by weight, the wear-resistant material layer will become brittle.
耐摩耗材層の熱膨張係数は、自溶性合金粉末に
対するセラミツク粉末の配合割合によつて異な
り、例えば74％Ni−14％Cr自溶性合金粉末にWC
粉末を40重量％配合して形成される耐摩耗材層の
熱膨張係数（α）は約７×10-6／℃であり、WC
粉末配合量が20重量％の場合は約９×10-6／℃で
ある。従つて、基材層の熱膨張係数が同じであつ
ても、耐摩耗材層の粉末配合割合が異なる場合
は、それに応じて中間層の熱膨張係数を調整する
ことが必要である。その調整は前記のように中間
層材であるFe−Ni合金のNi含有量を変えること
により容易に行うことができる。 The coefficient of thermal expansion of the wear-resistant material layer varies depending on the blending ratio of ceramic powder to self-fusing alloy powder. For example, 74%Ni-14%Cr self-fusing alloy powder has a WC
The coefficient of thermal expansion (α) of the wear-resistant material layer formed by blending 40% by weight of powder is approximately 7×10 -6 /°C, and the WC
When the powder content is 20% by weight, the temperature is approximately 9×10 −6 /°C. Therefore, even if the base layer has the same coefficient of thermal expansion, if the powder blending ratio of the wear-resistant material layer differs, it is necessary to adjust the coefficient of thermal expansion of the intermediate layer accordingly. The adjustment can be easily made by changing the Ni content of the Fe--Ni alloy that is the intermediate layer material, as described above.
他方、基材層は、目的とする耐摩耗部材に、そ
の用途・使用条件に応じた靭性を付与する適宜の
金属材料（例えば、炭素鋼、低合金鋼、高合金鋼
等）が使用される。 On the other hand, the base material layer is made of an appropriate metal material (e.g., carbon steel, low alloy steel, high alloy steel, etc.) that imparts toughness to the intended wear-resistant member according to its application and usage conditions. .
なお、基材層表面に対する中間層の形成を溶射
法により行うので、溶射粒子は大気中を飛行する
過程で酸化をうける。従つて、中間層を形成した
のち、還元処理を行うことは、中間層の材質を改
善するために望ましいことである。 Note that since the intermediate layer is formed on the surface of the base material layer by a thermal spraying method, the thermal spray particles are oxidized while flying in the atmosphere. Therefore, it is desirable to perform a reduction treatment after forming the intermediate layer in order to improve the material quality of the intermediate layer.
