国内外金属颜色的定量研究概述

Review on Quantitative Research on the Metal Color

介绍了近年来国内外对金属颜色定量研究的概况。有关金属颜色定量研究的资料甚少,而且研究内容仅限于Au Ag Cu、Cu Zn Al和Cu Mn Zn合金系的颜色测量和色度参数随成分变化规律的初步探讨方面。由于固体金属或合金的色度参数不仅与其材料的组成和内部结构有关,而且受测色仪器、测色条件和样品状态的制约,因此需要进一步从固体物理学、量子力学、金属光学等角度探讨颜色本质,建立合金颜色的理论计算模型。指出金属颜色的定量将在装饰合金的开发研究和金属表面着色等方面发挥重要作用。

Quantitative research on the metal color in recent years is summarized. It is shown that up to now only a few papers have been found on this subject, which mainly focus on the AuAgCu, CuZnAl and CuMnZn alloy systems. In general, the CIE LAB uniform color space is used to describe the surface color of metals. Factors influencing the metal color are as follows: metal composition, metal microstructure and colormeasuring instruments, observing and viewing condition, sample preparation etc. It is necessary to study the color origin of metals on the basis of Solid Physics, Quantum Theory and Metallic Optics. It is expected that color quantification will play an important role in developing alloys for decoration and coloring metals.
