Abstract
A traveller for spinning made of hard drawn steel wire or alloy steel wire, having at least at the surface of a part which makes contact with a ring a ceramic coated layer. The ceramic coated layer consists of one or plural layers selected from a layer of carbide, nitride, oxide, boride or the like. The traveller with a ceramic coated layer has high wear resistance, runs stably for many hours, prevents frequent yarn breakage and has longer service life.
Claims5
A traveller for spinning made of a hard steel wire or an alloy steel wire body, having a surface coated with a ceramic nitride layer selected from the group consisting of TiN, TiCN, ZrN, Si.sub.3 N.sub.4, TaN, AlN, GaN, BN and InV, said coating being at least at the surface of a part which makes contact with a ring.
A traveller for spinning made of hard steel wire or alloy steel wire body, having a plurality of ceramic coated layers of the same or different kind, each layer being selected from the group consisting of SiC, TiC, ZrC, TiN, TiCN, ZrN, Al.sub.2 O.sub.3, ZrO.sub.2, SiO.sub.2, TiB.sub.2 or ZrB.sub.2 at least at the surface of a part which makes contact with a ring.
A traveller for spinning made of hard steel wire or alloy steel wire body, having a composite ceramic coated layer formed by dispersing ceramic grains of 0.2.mu.-3.mu. in grain diameter with an alloy of an Ni group, Ni, Cr or CO as matrix at least at the surface of a part which makes contact with a ring.
