摘要

研究了Ｃｕ－Ｚｎ合金铸件的色泽特性与Ｚｎ质量分数变化的规律，并与三种Ｋ金（２４Ｋ，１８Ｋ和１４Ｋ）的色度参数进行了比较。结果表明，随Ｚｎ质量分数的增加，合金表面色中的红色成分先减少然后增加，而黄色成分和明度值先增加然后减少；合金的表面色泽由铜色向金黄色、黄色、绿黄、黄、金黄色变化。通过调整Ｚｎ质量分数，可获得色泽接近１８Ｋ和１４Ｋ金表面色的合金，但不能获得色泽接近２４Ｋ金表面色的合金。

Abstract

The effect of Zn addition on the color characteristics of the CuZn alloy castings was studied. The experimental results show that with an increase in Zn content

the red color fraction of an alloy decreases first and then increases

while as the yellow color fraction and lightness value increase first and then decrease

the alloy surface color changes from copper red to golden yellow

yellow

green yellow

yellow

and golden yellow. By adjusting Zn content

the alloys with 18K or 14K gold colors surface can be obtained

but those with 24K gold color surface can not be obtained.
