Golden rigid decorative member |
摘要 |
A golden rigid decorative member in which scratch resistance and abrasion resistance are significantly improved and deterioration of appearance quality due to a flaw, abrasion, or the like is suppressed, and which has a pale color with a high quality feel is stably provided. A single layer or several layers of a coating including a reaction compound of an alloy of Ti and one or two or more metals selected from Nb, Ta, and V, and of one or two non-metallic elements mainly including nitrogen and selected from carbon and oxygen are stacked on a base. |

1. A rigid decorative member comprising:
a base; and a rigid decorative coating with plural layers containing a reaction compound of an alloy of Ti and one or two or more metals selected from Nb, Ta, and V, and of one or two or more non-metallic elements selected from nitrogen, oxygen, and carbon on the base, wherein the plural layers include an adhesion layer stacked on a substrate, a gradient adhesion layer stacked on the adhesion layer, an abrasion-resistant layer stacked on the gradient adhesion layer, and a golden adjustment gradient layer stacked on the abrasion-resistant layer; a non-metallic element in the adhesion layer is low-concentration oxygen; a non-metallic element in the gradient adhesion layer, that of the abrasion-resistant layer, and that of the golden adjustment gradient layer mainly comprise nitrogen and are selectively selected from carbon and oxygen; the content of a non-metallic element in a reaction compound included in the gradient adhesion layer is increased in a gradient manner in a thickness direction with departing from the substrate; and the content of a non-metallic element in a reaction compound included in the golden adjustment gradient layer is increased or decreased in a gradient manner in a thickness direction with departing from the substrate. |
