摘　　要：微弧氧化着色技术可赋予镁锂合金的陶瓷涂层特定的色调、吸收率和发射率。本文基于CIE色度学系统,利用Lambda950紫外-可见-近红外分光光度计测量物体的反射率;再运用Matlab软件量化物体颜色的参数指标,包括1931CIE色度坐标、明度L^(*)、色度a^(*)、b^(*)、色差ΔE^(*)及对应的1931CIE色品图和反射率曲线。结果表明:运用色度学原理,可以定量、客观地描述微弧氧化热控涂层的颜色,进而建立色调和热控性能的联系,该技术可用于评价涂层的热控性能。Micro arc oxidation coloring technology can endow the ceramic coating of Mg-Li alloy with specific hue,absorptivity and emissivity.Based on CIE colorimetric system,lambda950 ultraviolet visible near infrared spectrophotometer is used to measure the reflectance of objects.Then,Matlab software is used to quantify the parameters of object color,including its 1931CIE chromaticity coordinates,lightness L^(*),chromaticity a^(*)、b^(*),color differenceΔE^(*),corresponding reflectivity curve and 1931cie chromaticity map.The results show that the color of micro arc oxidation thermal control coating can be described objectively and quantitatively by the principle of chromaticity.By establishing the relationship between hue and thermal control performance,the technology can be used to evaluate the thermal control performance of coatings.
