CORROSION-RESISTING NOBLE METAL MATERIAL, ITS MANUFACTURING METHOD, AND PRODUCT OF THE NOBLE METAL

摘要

PROBLEM TO BE SOLVED: To provide a high-quality corrosion-resisting noble metal material by which noble metal ornaments can be protected from corrosion over a long period and which has an excellent ornamental property and can be treated at a low cost, and also to provide its manufacturing method and products of the noble metal. SOLUTION: The corrosion-resisting noble metal material is composed of a noble metal material prepared by mixing 0.1 to 5.0% by weight ratio of titanium oxide into copper-containing silver alloy 4. A deodorizing property, a antibacterial property, a soil-resisting property and corrosion resistance are provided to this material by decomposing odor, bacteria, virus, soil, into gaseous CO2and water.
