ォークが一般に用いられている。(Prior Art) Iron-based members are used in automobiles and many other mechanical devices. For example, shift forks made of cast iron are generally used in automobile transmissions.
このシフトフォークの場合、相手材であるハブスリーブ
（材質はＳＣｒ、２などである。）との摺動部が摩耗し
易い。In the case of this shift fork, the sliding part with the mating material, the hub sleeve (made of SCr, 2, etc.), is likely to wear out.

メッキ層の剥離を防止しているが、メッキと加熱の画処
理が必要トなり、また、コスト高になる憾みもある。However, with the countermeasure /), the handle of the shift fork tends to break due to the lack of strength of the material itself, j), j)

Since the wettability between l and Fe (iron) is not very good,
After plating, heat treatment is performed to diffuse A into the base material (Fe) to form a Fe-A compound layer,
Although this prevents the plating layer from peeling off, it requires plating and heating, and there is also the problem of high costs.
（発明の目的）
本発明は上記従来技術の問題点を解決しようとするもの
であり、鉄系部材の表面にＦ ｅ−Ａｆｆ１合金による
耐摩耗層を簡単に形成する方法を提供するものである。(Objective of the Invention) The present invention aims to solve the problems of the prior art described above, and provides a method for easily forming a wear-resistant layer made of Fe-Aff1 alloy on the surface of an iron-based member. .
（発明の構成）
本発明においては、まず、鉄系部品の耐摩耗層を形成す

−Ａｌ合金粉を磁力により付着せしめる。(Structure of the Invention) In the present invention, first, a portion of an iron-based component where a wear-resistant layer is to be formed is magnetized, and the surface of this portion is
-Al alloy powder is attached by magnetic force.
そして、ｐ ｅ −Ａｊ？合金粉を溶融させて上記表面
にＦｅ−Ａｌ合金の耐摩耗層を形成する。And p e −Aj? The alloy powder is melted to form a wear-resistant layer of Fe-Al alloy on the surface.
上記磁化は、Ｆｅ−Ａｌ合金粉の付着量を比較的多くす
ることができるようにするためである。The purpose of the magnetization is to allow a relatively large amount of Fe-Al alloy powder to adhere.
この場合、Ｆｅ−Ａｌ合金粉におけるＡｉ量はｊ〜／乙
重量係程度が好ましい。つまり、６％未満のＡｉ量では
所望の耐摩耗性を得ることが難しくなり、また、７２％
を越えるＡｉ量ではＦｅ−Ａｌ合金粉の磁性が弱く、鉄
系部材の表面に対する付着が十分でなくなる。In this case, the amount of Ai in the Fe-Al alloy powder is preferably about the weight ratio of j to /o. In other words, if the Ai content is less than 6%, it will be difficult to obtain the desired wear resistance, and if the Ai content is less than 6%, it will be difficult to obtain the desired wear resistance.
If the amount of Ai exceeds 1, the magnetism of the Fe-Al alloy powder will be weak, and the adhesion to the surface of the iron-based member will not be sufficient.
Ｆ ｅ−Ａｌ１合金粉の溶融は、高周波誘導や電気炉な
どによる加熱によって行なうことができる。The Fe-Al1 alloy powder can be melted by high frequency induction, heating using an electric furnace, or the like.
この溶融により、合金成分であるＦｅが鉄系部材に対し
容易に冶金的結合を行ない、結合強度の高いＦ ｅ−Ａ
ｚ合金層が形成される。この場合、鉄系部材の表面を粗

結合強度が得られる。Through this melting, Fe, which is an alloy component, easily forms a metallurgical bond with the iron-based member, resulting in Fe-A with high bonding strength.
A z-alloy layer is formed. In this case, even higher bonding strength can be obtained by roughening the surface of the iron-based member or by making it metallurgically active.

-A wear-resistant layer of an Al alloy can be formed on the surface of an iron-based member. In addition, since Fe-Aff1 alloy powder is used, the metallurgical bonding strength to iron-based members is increased by Fe, which is an alloy component, and a strong wear-resistant layer is obtained. It is also possible to control the amount of adhesion and form a thick wear-resistant layer in a short time.
