GOLDEN HARD LAMINATED FILM FOR GOLDEN ORNAMENT,GOLDEN ORNAMENT HAVING LAMINATED FILM AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide golden hard laminated films for golden ornaments which permit production of the golden ornaments having excellent wear resistance, corrosion resistance and flawing resistance, golden ornaments having such films and a method for manufacturing the same.;SOLUTION: The golden hard laminated films for the golden ornaments are formed by alternately repetitively laminating metal nitride films presenting at least two golden color tones. The metal nitride films are desirably composed of the nitride of Ti, Zr, Hf or Ta, in which the content of the metal is 40 to 60 atm% and the content of the nitrogen is 30 to 50 atm%. The laminated films has desirably lamination period of 20 to 40 nm and 0.1 to 3.0 μm film thickness of the entire part. The golden ornaments comprise forming the laminated films atop a base material for ornaments which may have a Ti film, etc., on the surface. A golden film composed of gold (alloy) may be formed on the surface of the laminated films or specific mixed layers may be formed between the laminated films and the golden film.;COPYRIGHT: (C)2004,JPO&NCIPI
