擦られており、長期間使用した場合は糸の接触部に摩擦
による糸溝等が生じ。[Prior art and its problems] Conventionally, knitting elements such as circular knitting machines and sewn knitting machines, such as knitting needles, sinkers, needle hooks, cams that move the knitting needles up and down and sinkers back and forth, and yarn feeders, have been used in knitting machines. The inside is constantly in contact with the threads and rubbed, and if used for a long time, thread grooves will form due to friction where the threads come into contact.

In order to swing the sinker, the sliding surfaces of the butt part and the cam wear out. For example, what is shown in Fig. 1 is a sinker, which is one of the tools for knitting machines, and is used in circular knitting machines. This is the part that is done.

要がある。Also, Fig. 2 shows a knitting needle 1 used in a circular knitting machine, and what is shown in Fig. 4 is a tool usually called a hook, and the knitting needle 1 is separately attached within the groove 13, 13' of this hook. It is attached to a member and moves up and down, but in order to make this movement happen smoothly, it is necessary to construct a surface with a small coefficient of friction.

材料の温度が高くなるために不可能である。Furthermore, FIG. 3 shows a knitting needle 14 used in a weft knitting machine, which is caused to move up and down by the cam shown in FIG.
When the butt part 15 of the JIil needle 14 and the groove part 16 of the cam are moved in contact with each other, a strong frictional force is generated in both contact parts, which tends to cause wear. Therefore, these knitting and sewing elements are subjected to various surface treatments to increase their abrasion resistance. For example, there is hard chrome plating, but it cannot have a hardness of HV100 or higher,
Further, in the carburizing method, the hardness is limited, and in the case of a thin tool such as a single-knit tool, carburization progresses to the inside, impairing its toughness. On the other hand, with hard chrome plating, the tail threads seem to slide easily, but in reality, the threads tend to stick, and when tension is applied to the threads, they act as if they are biting into the threads. In addition, as an application example of vacuum technology, titanium nitride coating by ion plating is considered, but it has poor toughness and has a friction coefficient of about 0.49.
When high melting point substances such as , W, and Ti are made amorphous, it is impossible to use the ion blating method because the temperature of the material to be coated becomes high.

果的である。In addition, between the steel surface and the amorphous alloy coating layer, zinc,
It is effective to form a layer of metals such as nickel, copper, chromium, cadmium, compounds thereof, or fluorine compounds. This is because, among the tools, for example, knitting needles, etc., are provided with a lug that is essential for forming stitches, and a groove is cut into the stem portion so that the lug can be rotatably attached to the stem portion. This is because although the deep concave portions of the grooves do not come into direct contact with the yarn, it is necessary to form a coating for rust prevention purposes. Also, when smoothness in μ units is required for the entire tool,
It is more effective to form a metal film as a base treatment step.
更に、工具に対するアモルファス合金の被膜層の形成を
スパッタリングにより行うものである。Furthermore, a coating layer of an amorphous alloy is formed on the tool by sputtering.

の滑りが円滑になる。[Function] Although the amorphous metal layer does not originally have a crystalline structure, its properties are significantly different from those of ordinary metal surfaces, and it has not only corrosion resistance but also abrasion resistance, high water repellency, and a reduction in the coefficient of friction. If the film thickness is less than lOμ, it will have a pear-shaped surface with thin uneven surfaces due to the polished surface of the base material and the nature of sputtering, and the sliding of the thread will be smooth because the contact area with the thread is reduced.

Connect the + side of V and ionize argon gas under glow discharge.Ions are Ta
The target materials 3 and 3' are sputtered to expel sputtered atoms and adhere to the surface of the knitting needle 1 to form a film. At this time, since the target materials 3 and 3' have a sufficiently large area relative to the surface area of the knitting needle 1, a -like film can be formed all over the periphery of the knitting needle 1. After sputtering for about 30 minutes,
A film of μ was formed.

However, by adjusting the angle of the ml fairing plate 6, the area around the tip 8 and the hole 9 can be The film thickness of the stem portion was 1 to 3 μm. At this time, the voltage was 2000 V, the current value was 8 amperes, the time required was 40 minutes, and the temperature of the sewing needle during processing was 250°C. The friction coefficient of the Ta-based and W-based amorphous metal layers used in the present invention was 0.05 to 0.15, which was less than 30% of that obtained by ion blating.
