本文通过在金属铝表面阳极氧化合成红宝石膜的探索,确定了合成此膜的条件,研究了电流密度、氧化时间、温度、电解液组成和吸附等因素对成膜过程的影响,并讨论了成膜机理。经X射线衍射和扫描电镜测试证实,获得的膜系与氧化铬相组合的(α—Al_2O_3膜,即红宝石膜,其耐蚀、耐磨性能和硬度大为提高,且具有装饰性,是一种很有价值而值得探索的新型材料。
In this paper, aluminum films were synthesized by anodic oxidation of ruby to explore the film to determine the conditions for the synthesis of the film, the current density, oxidation time, temperature, electrolyte composition and adsorption and other factors on the film forming process, and discussed the Membrane mechanism. The results of X-ray diffraction and scanning electron microscopy showed that the α-Al 2 O 3 film (ruby film) combined with the chromic oxide film obtained by this method has much better corrosion resistance, abrasion resistance and hardness and is decorative Very valuable and worth exploring new materials.
