| 中文摘要: |
| 评述了合金元素对Au的漂白效果和机制，介绍了白色开金的几种色度参数，如CIE-L a*b*色度参数和颜色盒，CIE-LAB-C-H-L米制色度参数和基于CIE-XYZ色度参数的ASTM D1925黄色指数YI，讨论了某些白色开金的色度参数与冶金学特征。基于金合金的漂白效应与合金成分的密切关系，ASTM D1925黄色指数YI为设计白色开金成分提供了基本的指南。 |
| 英文摘要: |
| The bleaching effects and mechanism of alloying elements to gold were reviewed. The several chromatic parameters, such as CIE-L a*b* chromatic parameters, CIE-LAB-C-H-L metric chromatic parameters and ASTM D1925 Yellowness Indexes, for determining the whiteness of jewelry gold alloys were introduced. The chromatic parameters and metallurgical features were discussed. Based on the closer relations between the bleaching effects and alloying components, ASTM D1925 Yellowness Indexes could provide a basic guide for designing white jewelry carat gold alloys. |
