【摘要】：表面着色技术能在材料表面形成不同颜色的保护性膜层,在提高材料表面性能的同时,又可赋予产品漂亮的外观或实现消光等目的。表面着色有两种形式:一是,所生成的化合物自身具有一定的颜色;二是,光线的反射、折射、干涉等效应而使表面呈现不同颜色。作为两类重要的结构材料,镁合金和钛合金因其各自优良的性质被应用于诸多领域。综述了镁合金和钛合金表面着色工艺研究进展,介绍了镁合金和钛合金表面着色工艺研究及应用现状。镁合金表面着色工艺包括:化学转化+喷涂、金属涂层、有机涂层、阳极氧化和微弧氧化;钛合金表面着色工艺包括:热氧化、化学氧化、阳极氧化和微弧氧化。列举了应用于镁合金和钛合金表面着色的具体工艺参数,总结了两种合金表面着色的具体应用。镁合金和钛合金部件经表面着色处理后,可以兼顾轻量化和强度要求,并实现部件外观的装饰性。基于镁合金和钛合金表面着色工艺研究的现有成果,对镁合金和钛合金表面着色的研究提出了一定展望。
[Abstract]:Surface coloring can form a protective coating of different colors on the surface of the material. While improving the surface properties of the material, it can also give the product a beautiful appearance or the realization of extinction. The surface coloring has two forms: first, the generated compounds have their own colors; two, the reflection, refraction, interference and other effects of the light. As two important structural materials, magnesium alloys and titanium alloys are used in many fields because of their excellent properties. The progress in the research on the surface coloring process of magnesium and titanium alloys is reviewed. The research and application of the surface coloring process of magnesium and titanium alloys are introduced. The process package for the surface coloring of magnesium alloys is introduced. Including chemical conversion + spraying, metal coating, organic coating, anodic oxidation and micro arc oxidation, the surface coloring process of titanium alloy includes thermal oxidation, chemical oxidation, anodic oxidation and micro arc oxidation. The specific process parameters applied to the surface coloring of magnesium alloy and titanium alloy are enumerated, and the concrete applications of the two kinds of alloy surface coloring are summarized. The titanium alloy components can be treated with surface coloring, which can give consideration to the requirements of light weight and strength, and to realize the decoration of the appearance of the components. Based on the existing achievements in the study of the surface coloring process of magnesium alloys and titanium alloys, the research on the surface coloring of magnesium alloys and titanium alloys is given a certain prospect.
