2. Description of the Related Art In conventional spinning rings, low carbon steel is generally used, and carburizing and quenching is performed as a surface hardening treatment. However, in the above ring, when the spindle rotational speed is 20000 rpm or more, the friction resistance between the ring and the traveler increases, and the frictional heat rapidly increases, so that the traveler seizes early and wear is scattered, which prevents continuous operation. There was a problem.

The content of the hard fine particles is set to 5 to 40% by volume, but if it is less than 5%, the effect of improving wear resistance is insufficient, and if it exceeds 40%, the cost increases. Further, the content of the solid lubricant fine particles is set to 5 to 40% by volume, but 5%
If it is less than 40%, the lubricating effect is insufficient, and if it exceeds 40%, the coating strength becomes weak and peeling wear and the like are likely to occur. Also,
Although the total content of the eutectoid substances was set to 10 to 50% by volume,
If it is less than 10%, the expected effects in wear resistance and lubricity cannot be obtained, and if it exceeds 50%, the strength of the coating film is deteriorated and peeling wear or the like is likely to occur.
