10%, and the remainder consists of Fe and unavoidable impurities (wt%), the resulting structural member will basically have a Fe-based sintered alloy in the Fe-based alloy matrix due to the above composition. Carbide is dispersed and precipitated in the matrix, and Cr has a solid solution structure in the matrix, resulting in wear resistance,
We have come to the knowledge that these materials have excellent compatibility and corrosion resistance.
この発明は、上記知見にもとづいてなされたものであっ

０．５〜３．５チと定めた。It has the effect of combining with W, Nb, Ta, Ti, and Zr to form carbides and improving wear resistance, but if the content is less than 0.5%, the desired effect cannot be obtained. On the other hand, if the content exceeds 3.5%, the amount of carbide precipitation is too large and it becomes brittle.
The content was determined to be 0.5 to 3.5 inches since it could damage the mating member.

However, if the content is less than 5%, the desired effect cannot be obtained, while if the content exceeds 35%, the base material becomes brittle and the wear resistance deteriorates. However, the content was set at 5 to 35 chi.

０３〜３％と定めた。(C) PI B + and Si These components not only solidly dissolve in the base material to strengthen it and thereby improve wear resistance, but also react with Fe during sintering to form a liquid phase. Activates sintering by generating carbon, thereby densifying the sintered body and stabilizing carbides, which has the effect of improving corrosion resistance, but the content is 0.03%.
If the content is less than 3, the desired effect cannot be obtained; on the other hand, if the content exceeds 3, the corrosion resistance will deteriorate again and embrittlement will occur significantly.
It was set at 0.03 to 3%.

．． If the content is less than 5%, the desired effect of improving the above action cannot be obtained, while if the content exceeds 10%, the damage to the mating member will increase, so the content was set at 0.5 to 10%. .

５〜１０チと定めた。(e) Ni, Co, and Cu These components have the effect of further strengthening the substrate and further improving compatibility with the mating material, as well as further improving corrosion resistance against the fuel used. It is included as necessary when properties are required, but if the content is less than 0.5%, the desired improvement effect on the properties cannot be obtained, but on the other hand, it may be contained in excess of 10%. No further improvement effect appeared, and considering economic efficiency, the content was reduced to 0.
It was set at 5 to 10 inches.

０．０５〜１０％と定めた。(f) Nb, Ta, Ti, and Zr These components have a strong affinity with C, so they combine with C to form carbides with high hardness, and also form double carbides together with carbide-forming components such as Cr. , which further strengthens the bond between the carbide as the dispersed phase and the matrix as the binder phase, thereby further improving wear resistance and further improving corrosion resistance against low-quality fuel.
It is included as necessary when these properties are required, but if the content is less than 0.05%, the desired improvement effect on the above properties will not be seen, while if the content exceeds 10%, the Since damage to the member becomes large, its content is set at 0.05 to 10%.

がみられるようになるという理由からである。In addition, it is desirable that the Fe-based sintered alloy of the present invention has a theoretical density ratio of 85 cm or more, which means that if the theoretical density ratio is less than 85 cm, it will not be possible to use the Fe-based sintered alloy for supplying fuel such as degraded gasoline or alcohol. This is because corrosion resistance and conformability deteriorate.
