摘要
采用CIELAB表色系统 ,用明度L 、色品a 和b 描述合金的颜色。通过分光光度计定量地测定了Cu Zn二元黄铜的色度参数 ,探讨了L ,a ,b 和C 随Zn含量的变化规律 ,给出了常用二元黄铜表面色的定量定性结果。研究表明 ,Cu Zn二元合金的色度参数a 和b 值可以通过数学公式模拟计算 。
The color characteristics of Cu Zn binary alloys were investigated quantitatively. Using CIE LAB color system, the surface color of the alloy was described by chromaticity parameters L *, a * and b *, which were measured by the spectrophotometer. The changing law of color parameters ( L *, a *, b * and C *) with Zn content was demonstrated. Therefore, the surface colors of some standard Cu Zn binary alloys were given. The results show that a * and b * values are changed with Zn content abiding by the polynomial equation so that the surface color of the Cu Zn alloy system can be forecast.
