（産業上の利用分野）
本発明は耐火金属被覆層の形成方法並びに耐火金属被覆
層で被覆されたタングステン繊維およびタングステン繊
維強化超合金体に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a method for forming a refractory metal coating layer and to tungsten fibers and tungsten fiber reinforced superalloy bodies coated with a refractory metal coating layer.
（従来の技術）
熱機関の高出力化に際しては、高温化が不可欠の要素で
あり、そのためジェットエンジンのタービン翼等高温部
材に用いる材料の開発が精力的に進められている。(Prior Art) In order to increase the output of a heat engine, increasing the temperature is an essential element, and for this reason, the development of materials for use in high-temperature components such as the turbine blades of jet engines is being actively pursued.
従来の最強材料は、ＮｉにＣｒ、Ａρ、Ｍｏ等の強化元

、超高温まで高強度が期待できるＷ繊維やセラミック繊
維と、耐熱、耐蝕性に優れるＮｉ基、Ｆｅ基合金と組み
合わせた複合材料、即ち、繊維強化超合金が注目されて
いる。The strongest conventional material was a Ni-based superalloy made by adding reinforcing elements such as Cr, Aρ, and Mo to Ni. As next-generation materials, composite materials that combine W fibers and ceramic fibers, which are expected to have high strength up to extremely high temperatures, with Ni-based and Fe-based alloys, which have excellent heat resistance and corrosion resistance, ie, fiber-reinforced superalloys, are attracting attention.
強化繊維としては、信頼性が高くセラミックスより加工
性の良いＷおよびＷ合金が最も有力である。The most effective reinforcing fibers are W and W alloys, which are highly reliable and have better workability than ceramics.
しかしながら、タングステン繊維（以下Ｗ繊維という）

が低下する問題がある。However, tungsten fiber (hereinafter referred to as W fiber)
The high-temperature strength of is exhibited under the following conditions: (a) being in a non-oxidizing atmosphere and (b) retaining the fibrous structure due to cold working, and even if either of these conditions are absent, the strength will be maintained. There is a problem of deterioration.
繊維強化超合金においては、Ｗ繊維を超合金中に埋め込

しては、Ｎｉ基、Ｆｅ基超超合金ｗｅｉ維との界面で、
高温時に成分元素の拡散や反応層生成等の相互作用のた
めに、Ｗ繊維が脆化する問題があった。In a fiber-reinforced superalloy, oxidation is prevented by embedding W fibers in the superalloy, and the above condition (a) can be satisfied. However, regarding the condition (b), at the interface with the Ni-based and Fe-based superalloy wei fibers,
There is a problem in that W fibers become brittle due to interactions such as diffusion of component elements and formation of reaction layers at high temperatures.
この様な界面反応を防止するために、Ｗｌｌｉ維の表面
にＮｂ等の耐火金属からなる耐火金属被覆層を設けるこ
とが知られている（特開昭６．３−１５３２３４号）。In order to prevent such an interfacial reaction, it is known to provide a refractory metal coating layer made of a refractory metal such as Nb on the surface of the Wlli fiber (Japanese Patent Laid-Open No. 153234/1983).
ところで、細いＷ繊維の表面に耐火金属被覆層を均一に

とする問題があった。However, it is extremely difficult to uniformly form a refractory metal coating layer on the surface of thin W fibers. Conventionally known methods for forming this refractory metal coating layer on the surface of W fibers include sputtering and thermal spraying in a non-oxidizing atmosphere. However, all of these methods require large-scale equipment, and in order to uniformly coat the entire surface of the W fibers, the W fibers must be constantly moved so that they face the supply source evenly. There was a problem in that it required a great deal of effort.

とする問題がある。(Problems to be Solved by the Invention) As mentioned above, coating the surface of the tungsten fibers that strengthen conventional superalloys with a refractory metal coating layer not only requires large-scale equipment but also requires a large amount of work. There are problems that require effort.
本発明の目的は、タングステン繊維の表面に容易に均一

繊維強化超合金体を提供することにある。The objects of the present invention are a method for forming a refractory metal coating layer that can easily form a uniform refractory metal coating layer on the surface of a tungsten fiber, a tungsten fiber coated with a refractory metal coating layer, and a tungsten fiber reinforced with the tungsten fiber. The object of the present invention is to provide a reinforced superalloy body.

A process of exposing Wi fibers to a molten CU-based alloy containing refractory metals to agglomerate and precipitate the refractory metals on the surfaces of W fibers, and Cu
A method for forming a refractory metal coating layer, comprising a step of removing a base alloy and unprecipitated refractory metal. The present invention also provides a tungsten fiber whose surface is coated with a refractory metal coating layer formed by this method for forming a refractory metal coating layer. Further, the present invention is a tungsten fiber reinforced superalloy body reinforced with this tungsten fiber.

が覆われたタングステン繊維が得られる。According to the method for forming a refractory metal coating layer of the present invention, when W fibers are exposed to a molten Cu-based alloy containing a refractory metal, the surface of the W fibers contains molten metal as the Cu-based alloy melts. The refractory metal component aggregates and precipitates, and the entire surface of the W fiber is uniformly covered with a layer of refractory metal. At this time,
W fibers are not embrittled by Cu-based alloys. After cooling, the Cu-based alloy and unprecipitated refractory metal components around the W fibers are removed with nitric acid or the like to obtain tungsten fibers whose surfaces are covered with a refractory metal coating layer.
本発明において、用いられる耐火金属としては、特に限
定されないが、ＮｂおよびＴａが超合金との反応を防止

alloys are preferred. That is, for this alloy, first,
From the viewpoint of the process, it is desirable that the melting point be as low as possible, but what is particularly important is that it is essential that the Wi fibers do not become brittle during heating. Alloys that meet these conditions include Cu, A
Examples include CI, ALI, Zn, etc., but ACI and Au are expensive and require complicated post-processing steps. Compared to Zn, Cu provides a better coverage of the refractory metal layer onto the W fibers, and is therefore most preferable. Here, the Cu-based alloy is an alloy mainly composed of Cu and does not contain elements that cause embrittlement of W fibers, such as N and Fe.

融しても良い。In the present invention, in order to expose the W fibers to a molten Cu-based alloy containing a refractory metal, the W fibers are embedded in a Cu-based alloy powder containing a refractory metal, and the whole is heated to melt the Cu-based alloy. Alternatively, W fibers may be embedded in a mixed powder of a Cu-based alloy powder and a refractory metal powder, and the mixed powder may be melted by heating the whole.
