摘　　要：颜色和色度坐标是珠宝饰品设计与制造的重要因素与参数。Au-Ag-Cu系合金是最重要的颜色开金饰品合金。文章评述了Ag、Cu对Au和Au基合金的光反射率和颜色的影响;介绍了Au-Ag-Cu系合金的色度图、金合金色泽标准及某些标准颜色合金成分;讨论了某些合金化元素对Au-Ag-Cu系合金颜色的影响。通过调整Ag、Cu组元含量比例和添加其它合金化元素,Au-Ag-Cu系开金合金可以获得丰富多彩的颜色,对于设计与控制珠宝饰品的颜色有重要意义。Au - Ag - Cu system alloys are the most important color jewelry alloys. The colors of Au - Ag - Cu alloys depend on the composition and the content of the alloying components. The influences of Ag and Cu components on the reflectivity and color of gold and gold -based alloys were reviewed. The chro- matic charts of gold - silver - copper carat alloys, color standard of carat alloys and the compositions of some standard color gold alloys were introduced. The effects of some other alloying elements on the color of gold alloys were also discussed. Au -Ag -Cu carat alloys can develop rich and varied colors through regulating the ratio of the contents of Ag and Cu in alloys and adding other alloying elements, which is the basis for designing and controlling colors of carat alloys based on gold.
