摘要

基于CIELAB色度学知识

定量研究了Cu含量在70%时

Al和Zn的成分变化对合金的颜色值、抗变色性以及氧化性的影响。结果发现

Al的添加会导致合金表面颜色黄色的因素减弱

从而使合金表面颜色与黄金色差加大

从而提高了合金的抗变色性以及合金的硬度。另外

探讨了影响抗变色性和抗氧化性的可能因素。

Abstract

Based on CIELAB chromatic theory

effects of different Al and Zn content on chroma

anti-tarnish and anti-oxidation behavior of brass based stimulant gold alloy with 70% Cu content were investigated quantitatively.The results show that color-difference is enlarged between surface color of alloy and gold as a result of Al addition weakening the yellow color in surface color of the alloy

improving the anti-tarnish behavior and hardness of the alloy.The possible factors influencing anti-tarnish and anti-oxidation behavior of the alloy were approached.
