<p>PCT No. PCT/JP94/00310 Sec. 371 Date Oct. 26, 1994 Sec. 102(e) Date Oct. 26, 1994 PCT Filed Feb. 25, 1994 PCT Pub. No. WO94/20660 PCT Pub. Date Sep. 15, 1994In knitting parts of a knitting machine(a guide, needle tongue and the like of a warp knitting machine), an anti-corrosion layer 12 formed by wet plating, an intermediate layer 14 formed by dry plating and a hard carbon film 16 formed by dry plating are successively laminated on and applied to, at least, a surface of that portion of a carbon steel base material 10 shaped to profile the knitting parts, which portion contacts with knitting yarn, and the anti-corrosion layer 12 formed by wet plating is applied to a surface other than the portion. So, the anti-corrosion layer prevents rust and corrosion which would otherwise be developed on a surface of the carbon steel base material 10, and the hard carbon film is firmly and adhesively applied, at least, to the surface of the portion contacting with the knitting yarn with the intermediate layer therebetwen, so that the thickness of the entire film is made small to provide an adequate wear resistance without impairing toughness of the base material, thereby markedly improving the durability.</p> |
