Balloon tension T and centrifugal force F are applied, and their combined force acts as contact pressure with ring 2. Further, the sliding speed between the traveler 1 and the ring 2 is determined by the rotation speed of the spindle and the ring diameter, and the magnitude of the friction between the ring 2 and the traveler 1 changes depending on the contact pressure and the sliding speed. .

早期摩耗による寿命の低下が大きな問題となる。 On the other hand, in recent years, spinning machines such as ring spinning machines and ring twisting machines have been made faster in order to increase productivity, and traveler wear has become an important problem in increasing speed. Conventional travelers for spinning machines are often made of hard steel wire such as carbon tool steel or alloy steel wire formed into a predetermined shape and then hardened or nickel plated. In this case, the spindle rotation speed is 14000 rpm
There are not many problems in the range of rotation speeds up to the front, but when the rotation speed of the spindle exceeds 20,000 rpm, shortened life due to early wear becomes a major problem.

案されている。 Therefore, in recent years, it has been proposed to apply various types of plating to the base surface of the traveler in order to improve its wear resistance. JP-A No. 62-125024 discloses that after electroless nickel plating is applied to the surface of the base material of the traveler, heat treatment is applied at 330 to 380°C for 60 to 120 minutes, resulting in crystallization with a hardness of Hv800 to 1000. It has been proposed to form a precipitation hardened alloy layer of nickel phosphide (Ni 3 P) to provide wear resistance.

が長くなるという問題もある。(Problem that the invention aims to solve) However, although the crystallized nickel-rimmetsuki alloy layer has a high hardness of Hv800 to 1000, the toughness and malleability that it had in the amorphous state before heat treatment have decreased. Because of this, it is brittle, and when the traveler receives an impact load, the plating alloy layer tends to crack, which may cause peeling and wear. Additionally, the hardness of the ring flange on which the traveler slides is generally Hv600 to 800.
If the hardness of the traveler surface is too high, there is a risk that the traveler may damage the ring flange. Furthermore, it is important for the traveler to slide on the ring flange in a constant posture in order to prevent yarn breakage and deterioration of yarn quality, but in the initial stage of use, the traveler has a small contact area with the ring, so it is important to slide the traveler in a certain posture on the ring flange. This results in instability, resulting in frequent thread breakage and fuzzing. In order to eliminate this inconvenience, the conventional traveler requires a break-in period at low speed at the beginning of its use until a conforming shape with the ring flange is formed. Therefore, when the surface height of the traveler is too high, it takes a long time to form a conforming shape, and there is a problem that the period during which the traveler's sliding posture is unstable becomes longer.

By this, a first layer made of crystallized nickel phosphide (Ni 3 P) with a hardness of Hv800 or more is formed in contact with the base metal, and the surface of the first layer is electroless nickel phosphorized and then heat treated. A second layer consisting of an amorphous nickel-phosphorus alloy layer and having a hardness of Hv600 or more was formed.

第２層の硬度がリングの硬度に比較して大き過ぎ
ずリングフランジを傷付けるおそれが小さい。(Function) The plating layer formed by electroless nickel plating is amorphous and has high toughness and malleability in its untreated state, but the adhesion between the substrate and the plating layer is low and the plating reaction is poor. It is brittle due to hydrogen pores that sometimes occur, and its hardness is around Hv550, which is lower than the hardness of general ring materials. On the other hand, when the plating layer is an alloy layer made of nickel phosphide (Ni 3 P) crystallized by heat treatment, the hardness improves to about Hv800 to 1000, but the toughness and malleability decrease and the surface cracks are likely to form. In the traveler of this invention, the highly hard first layer in contact with the base metal mainly plays the role of resistance to friction.
In addition, since the second surface layer is heat-treated at a relatively low temperature, hydrogen embrittlement and residual stress during plating are removed, and it remains amorphous, resulting in improved toughness and malleability. Its rich hardness is about Hv600, which is about the same as that of general ring materials, so it prevents peeling and wear triggered by cracks that occur on the surface of the first layer, and improves initial conformability to the ring. or,
The hardness of the second layer is not too large compared to the hardness of the ring, so there is little risk of damaging the ring flange.

However, carbon 0.8%, chromium 7.7%, molybdenum 0.75%,
After drawing alloy steel containing 0.33% vanadium into the predetermined cross-sectional shape of the traveler, the traveler 1 shown in Fig. 1 is made.
It was molded into the shape of , held at 1080°C for 30 minutes and quenched, then held again at 520°C for 1 hour, air cooled and tempered to obtain a traveler material. After degreasing this traveler material, it was subjected to a known electroless nickel plating process for 25 minutes, and after washing and drying, it was heat treated at 350°C for 1 hour. The physical properties of the film thus obtained were a film thickness of 7 μm, a hardness of Hv900, and a phosphorus concentration of 8.5%. Next, the traveler obtained as described above was degreased, then subjected to electroless nickel plating treatment for 20 minutes, and then washed and dried.
Heat treatment is performed at 180°C for 1 hour, and the surface of the base metal 3 is coated with the first layer 4, as shown in FIG.
Traveler A of the present invention was obtained in which the surface of layer 4 was coated with the second layer. The physical properties of the second layer were as follows: thickness: 5 μm, hardness: Hv600, and phosphorus concentration: 8%. In addition, for comparison testing, the material Traveler was degreased, electrolytically nickel plated for 25 minutes, and then washed and dried.
Traveler B was obtained by performing heat treatment at 350°C for 1 hour. Further, after degreasing the material Traveler, it was subjected to electroless nickel plating treatment for 20 minutes, and after being washed and dried, it was heat treated at 180° C. for 1 hour to obtain Traveler C.

It is extremely difficult to obtain the average value of a large number of values. The wear index value provided by the applicant is the third
As shown in the figure, the width W and depth D of the worn portion of the traveler 1 were actually measured using a microscope, and the value of √× was used as an index corresponding to the wear loss.

Compared to comparative products B and C, the rate of increase in the wear index value is smaller. Comparative product B, which has high hardness but lacks toughness and malleability, is particularly useful in the process of forming a conforming surface between the traveler and the ring flange in the initial stage of spinning, where impact loads are frequently applied to the traveler and the sliding posture of the traveler is unstable. has a large amount of wear, whereas A and C, which have an amorphous nickel phosphor layer with excellent toughness and malleability as a surface layer, have less wear compared to B, and when they lack toughness and malleability, It is clear that even if the hardness is large, the wear resistance becomes poor.
Moreover, in the steady wear region after the conforming surface is formed, the slope of comparative product B is smaller than the slope of comparative product C, which shows that in the steady wear region, the one with higher hardness has better wear resistance. In the traveler of the present invention, at the early stage of spinning, the level of wear until a conforming surface is formed is low due to the action of the second layer, and in the steady wear region, the progress of wear is slow due to the action of the first layer.

It is appropriate that the total thickness of both is 15 μm or less. If the film thickness is less than 1 μm, the coating has no effect on wear resistance, and if it exceeds 15 μm, the surface of the plating becomes rough and peels easily. or,
The phosphorus concentration is preferably in the range of 5 to 12%. Furthermore, if the heat treatment temperature when forming the second layer exceeds 250°C, the crystallization of the nickel-phosphorous alloy layer will proceed during the heat treatment, so it is necessary to perform the treatment at 250°C or lower.
In the above embodiment, the material of the traveler is high C.
-Cr-Mo-V alloy steel is used, but carbon tool steel, high-speed tool steel, nickel-based heat-resistant alloy steel, etc. may be used as the material. Furthermore, instead of forming the first layer 4 and the second layer 5 on the entire base of the traveler, they may be provided only on the inside of the traveler or only on the portion corresponding to the sliding surface with the ring flange.

Since the phosphorus alloy layer is used, the initial conformability is improved and the spinning stability at the beginning of use is improved. Furthermore, after the conforming surface is formed, the progress of wear is inhibited by the first layer made of highly hard crystalline material. Moreover, since the cracks generated in the first layer are covered by the amorphous layer of the second layer, damage due to exfoliation wear is prevented, so that wear resistance is improved.
