摘    要：采用分光光度计、扫描电镜等手段研究了混合稀土对阳极氧化6063合金的表面光学性能的影响.研究结果表明:在6063合金中加入0.2wt-%左右的混合稀土,合金的阳极氧化表面的反射率(对可见光)和明度提高,彩度和兴奋纯度降低;但稀土对其主波长和色调角度无明显影响.稀土的上述作用与其对合金阳极氧化膜的表面质量、形貌和微观结构的影响有密切的联系.

Abstract: Influence of mischmetal on optical property of anodized 6063 alloy was investigated by means of spectrophotometer and SEM. The investigation results showed that the addition of 0.2wt-% mischmetal to 6063 alloy increased the reflectivity (to visible light) and brilliancy of anodized film of the alloy, and decreaced its suturation and excitation purity of the colour, but mischmetal had no evident influence on its main wave length and tone. The above action of mischmetal was closely related to the effect on surface quality, morphology and microstructure of anodized film of 6063 alloy.
