とが出来ない等の欠点がある。 Conventionally, there are many methods for forming a metal coating layer produced by coating a metal or non-metal with a metal, but this method is particularly suitable for the surface of a flexible helical tube and an inner wire into which it is inserted as an outer tube. There was no method for forming a metal coating layer. To explain in detail, the above flexible spiral tube is
It is made by winding a flat steel wire in a spiral shape, and is widely used as an outer tube through which a steel cable made by twisting multiple thin steel wires is slidably inserted as an inner wire. It is used as the outer pipe of a steel cable that connects the operating lever and brake shoe in a bicycle brake system. Therefore, the flexible helical tube is
Since it is used to protect the inner wire from the outside world and to ensure smooth operation of the wire, it is required to have particularly excellent slip properties, but conventional flexible spiral tubes and inner wires are Generally, a metal coating layer is formed by double plating of zinc and nickel, which not only has poor slip properties, but also has a strong outer surface coated with a strong nickel plating layer, so after the formation of the metal coating layer, It has drawbacks such as the inability to perform processing such as wire drawing or punching.

By forming this, all of the drawbacks of the conventional technology are eliminated.
以下、この発明の金属被覆層形成方法を詳説す

Thereafter, a composite plating layer is formed by electroplating using a plating material in which a solid lubricant is mixed with tin as a plating base material. As the solid lubricant, it is preferable to use molybdenum disulfide, fluorine resin, graphite, glass fiber, or the like.

て強固に結合されるため、堅牢な被覆層となる。 Since the metal coating layer formed by the above method has a zinc layer formed under the double plating layer, only a small amount of expensive tin or solid lubricant is required, and it can be formed at low cost. Since tin is used as the plating base material, workability is extremely good. Therefore, processing can be performed after forming the metallization layer, and in particular,
When manufacturing inner wires, round steel wires coated with a composite plating layer can be drawn, and when manufacturing flexible spiral tubes, after forming a composite plating layer on round steel wires, flat steel wires can be drawn using dies, etc. In either case, by processing after forming the metal coating layer, the unevenness caused by electroplating is completely removed, resulting in a smooth flat surface.
Furthermore, because the composite plating layer that covers the outer surface contains a solid lubricant, it has extremely good sliding properties, and is suitable for parts that frequently slide, such as the aforementioned flexible spiral tube and inner wire. By forming it on the surface, there is a great advantage that wear can be prevented without using lubricating oil such as grease. In addition, since the workability is good, it is also possible to perform punching after forming a metal coating layer on the band iron. Moreover, since zinc and tin are bonded extremely strongly, the coating layer becomes robust.
