铝及铝合金是常用的金属材料，经适当氧化处理可具有较好的耐蚀性能。但由于其材料本身性质和氧化膜结构等原因，在有氯离子存在的环境中仍会发生严重腐蚀。本文尝试用溶胶－凝胶方法制备一层耐蚀无机覆盖膜。１实验部分（１）溶胶的制备以正硅酸乙酯（ＴＥＯＳ）为原料，... Aluminum and aluminum alloy are commonly used metal materials, which have good corrosion resistance after proper oxidation treatment. However, due to its own nature of the material and oxide film structure and other reasons, in the presence of chloride ions will still be serious corrosion. This article attempts to sol - gel method to prepare a layer of corrosion resistant inorganic coating. 1 Experimental part (1) Preparation of sol TEOS as raw material, ...
