以下、本発明の実施例を図面に基づいて詳細に説明す
る。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
硬鋼線材又は合金鋼線材を用いて、第１図に示すよう

散層（２）と、その上層に約２μｍ〜約15μｍのNi−Ｐ
合金層（３）を形成した所望のトラベラＴを構成する。
（第１図）。As shown in FIG. 1, a traveler T having a predetermined shape is formed by using a hard steel wire rod or an alloy steel wire rod, and quenching and tempering processes are performed. On the surface of the base material at the contact portion (Ta) with at least the ring flange of the traveler, a Ni-P (P content of 7 μm) having a thickness of about 2 μm to about 15 μm was formed by electroless Ni-P plating.
After adjusting to 10%) amorphous alloy plating film,
By heat treatment at 400 ° C for about 60 minutes, as shown in Fig. 2 and Fig. 3, at the interface between the plating film and the traveler base material, Fe of the base material (1) and Ni of the plating film were Diffusion occurs, and a Ni-Fe diffusion layer (2) having a thickness of about 0.5 μm is formed as a base layer, and a Ni-P layer having a thickness of about 2 μm to about 15 μm is formed on the Ni-Fe diffusion layer (2).
A desired traveler T having the alloy layer (3) is formed.
(Fig. 1).

より、NI3Pの析出が生じ、非晶質組織の結晶化がすす
み、その析出硬化作用により被膜硬度が、メッキ上りで
Hv450〜Hv550に対し、Hv900〜Hv1000に上昇した。The Ni-P alloy layer (3) is, by heat treatment under predetermined conditions, NI 3 P precipitation occurs, crystallization of the amorphous tissue proceeds, the coating hardness due to the precipitation hardening effect, plating up
Increased from Hv450 to Hv550 to Hv900 to Hv1000.
第４図にメッキ後の熱処理時間とトラベラの母材硬度
及びNi−Ｐ合金層の硬度の関係を示す。Fig. 4 shows the relationship between the heat treatment time after plating and the hardness of the traveler base material and the hardness of the Ni-P alloy layer.

ｍを越えると、Ni−Ｐ合金層表面の肌荒れが発生しやす
く、トラベラの走行を乱す原因となるばかりか、処理時
間も長くなり、コストアップになるので好ましくない。By the way, the plating film has a thickness of about 2 μm
It was set to about 15 μm, but if it is less than about 2 μm, the durability deteriorates and it hinders continuous operation at high speeds.
When it exceeds m, the surface of the Ni-P alloy layer is liable to be rough, which not only causes the traveling of the traveler to be disturbed, but also prolongs the processing time and increases the cost, which is not preferable.
次に、本発明のトラベラＡとNiメッキのみを施した従

できたことが判明した。Thread: cotton / ester 40 ' S ring: 3.2mm flange 41mmφ Traveler: YS-2 / hf 10/0 Spindle speed: 22000r.pm As a result of spinning test, as shown in FIG. Is about 1/2 the wear amount compared to the conventional product B,
As is clear from FIG. 6, the product A of the present invention has a smaller number of yarn breakages as compared with the product B of the related art, and continuously maintains a stable operating state under high speed operation, as is clear from FIG. It turned out that it was possible.

コストで生産できる等の効果を奏する。According to the present invention, since it has the above-mentioned constitution, it is integrated by mutual diffusion of the base material and the plating film as a base layer.
Since a high hardness Ni-P alloy layer is formed on the upper layer of the Ni-Fe diffusion layer, the Ni-P alloy layer is less likely to peel off, the effect of suppressing adhesion is sufficiently exerted, and the wear resistance is significantly improved. Furthermore, Ni-P
Even after the alloy layer is worn, the Ni-Fe diffusion layer is integrated with the base material, so the adhesion effect is further extended, and the number of yarn breakages is high even in the high-speed operation range where the spindle speed is 20000 rpm or more. A small amount of stable continuous operation can be maintained. Further, the present invention has effects such that a spinning machine traveler having a Ni-Fe diffusion layer having a high adhesion to the base material and a Ni-P alloy layer which is difficult to separate from this layer can be produced at a relatively low cost.
