Abstract: A white decorative part comprising a base material, a hard white coating formed on said material by dry plating, and an outermost coating formed on said coating by dry plating, wherein the white coating comprises titanium or a nitride, carbide, oxide or carbonitride of at least one element selected from the group consisting of titanium, hafnium, zirconium, tantalum, vanadium, chromium and aluminium, while the outermost coating comprises an alloy of gold with nickel, tantalum, cobalt, palladium, silver, rhodium, titanium or iron and is composed of 30-80 at.% of gold and 70-20 at.% of nickel, tantalum, cobalt, palladium, silver, rhodium, titanium or iron. This part is uniformly white and bright, has a warmth, is excellent in thight contact between the base material and the outermost coating, and has an appearance of a high-quality article. When the outermost coating comprises a gold-titanium or gold-iron alloy, it does not cause metal allergy on the skin.

Abstract: A diamond-like carbon (DLC) film is spread over the dents of a reeed as a part of a high speed loom at a part of the dents requiring the highest resistance-to-wear. When using stainless steel as a base material of the dents, DLC film is spread through an intermediate layer comprising, for example, a titanium carbide layer. Reed dents covered with a DLC layer are arranged at side ends of the reed which are likely to wear severly and, at the middle portion of the reed, dents covered with comparatively inexpensive hard film or non-treated dents are arranged so that degrees of wear of reed dents may be uniform throughout the reed for enabling reduction in cost. A reed of this invention is applicable to a variety of fibers such as natural fibers, synthetic ones, and new material ones, whereby durability of a reed is markedly increased at low cost.
