て耐摩耗性効果をもたらしている。Conventional technology and its problems Conventionally, metal travelers used in spinning spinning machines, twisting machines, etc. are required to have wear resistance under severe operating conditions due to sliding sliding on the ring flange surface at high speed. It Therefore, in order to impart this wear resistance, a hard steel wire or alloy steel wire is used as a material, after being formed into a predetermined shape, it is subjected to a quenching treatment, and the surface thereof is nickel plated, chrome plated, etc. Is brought.

る。However, under the high speed and high production system in recent spinning factories, the abrasion resistance is insufficient and the wear is early, the traveling of the traveler is unstable, the yarn breaks frequently, and the fluff occurs. Often occurs, causing early seizure and scattering of travelers. In such high-speed production, there is a strong demand for extending the life of travelers.

飛散等により紡出不能となる問題点がある。Therefore, as a means for improving the wear resistance and durability of the above-mentioned traveler, a chromium-plated traveler can obtain a high hardness of coating hardness Hv800 or more, but cracks easily occur on the plating surface, which causes peeling wear. Will cause the traveler to wear abnormally. Furthermore, the coating hardness of nickel plating is as low as 300 to 400 Hv, and the durability of the coating at high speed operation is short, and when the coating disappears, the wear rapidly progresses, the tension is high, the yarn breaks, the traveler burns, the traveler scatters, etc. Therefore, there is a problem that spinning becomes impossible.

供することを目的とする。Means for Solving Problems The present invention solves such problems. That is, an amorphous alloy plating layer of electroless nickel / phosphorus is provided on at least the surface of the base material of the metal traveler that comes into contact with the ring flange, and heat treatment is performed to obtain a hardness of Hv800.
To provide a metal traveler having good adhesion to the base material, being hard, and having excellent wear resistance and durability by forming a precipitation hardened alloy layer of crystallized nickel phosphide (Ni 3 P) of up to 1000. With the goal.

たリン化ニッケルNi3Pが析出硬化した合金属２を形成す
る。As shown in FIG. 1, a metal traveler 1 having a required shape is formed using a hard steel wire rod or an alloy steel wire rod, and is subjected to quenching and tempering treatments. At least a surface of the base material of the traveler which is in contact with the ring flange is formed with an amorphous alloy plating film by electroless nickel-phosphorus plating having a thickness of 0.02 μ or more and 15 μ or less. The content of phosphorus in the amorphous electroless nickel-phosphorus alloy coating is 4 to 15% (preferably 6 to 12).
%), And further heat treatment (1 at about 350 ° C
By doing so, the alloy metal 2 in which crystallized nickel phosphide Ni 3 P having a hardness of about 900 Hv is precipitation hardened is formed.

いたニッケル・リン合金メッキ層は加熱に伴って次第に
層状組織が消失し、リンは次第にリン化ニッケル（Ni

Crystallize as 3 P).

しくない。Also, the thickness of the plating film was set to 0.02μ or more and 15μ or less,
If it is less than 0.02μ, durability is reduced and it interferes with continuous operation, which is not preferable, and if it exceeds 15μ, the plating surface becomes rough and traveller fluctuations occur, and the processing time increases and the cost increases. Therefore, it is not preferable.

である。As the heat treatment conditions, as shown in FIG. 3, when the coating hardness C of the plating layer is raised to the maximum of about Hv1000, the heat treatment temperature is 400 ° C. in 1 hour, while the traveler base metal hardness D is The return effect lowers the hardness to around Hv500, and the traveler hardness is insufficient, so that elasticity is insufficient and abrasion resistance is reduced, which is not preferable. Therefore, as the optimum conditions for keeping the traveler base material hardness around Hv600 and obtaining the coating hardness of the plating layer around Hv900, the treatment temperature of 330 ° C. to 380 ° C. and the treatment time of 60 minutes to 120 minutes are suitable.
