【摘要】 黄金及其合金是历史悠久的饰品材料,金合金的颜色本质是电子的能带跃迁,因此可以通过合金化与能带结构变化的关系来了解颜色变化的机制。目前,CIELAB方法是珠宝领域普遍采用的颜色测量方法。金合金按照颜色分主要有白色金合金和彩色金合金两种。综述了近年来国内外首饰用白色以及彩色金合金的一些发展状况,评价了各种合金的冶金性能,并介绍了近年来最新出现的一些新型金合金。更多还原

【Abstract】 Gold and it’s alloy have a long history of being used as a kind of jewelry materials. The inbeing of the color is the electron transition in energy band. So the mechanism of color change can be explained as the change of energy band structure because of alloying. CIELAB method is generally accepted in jewelry production. Gold alloy can be classified as white gold alloy and color gold alloy by color. Some evolution of these alloys are introduced in this paper. Metallurgical features of different gold alloys are discussed and some newly born gold alloys are also introduced.更多还原
