Abstract

A hybrid sol was prepared by sol-gel technique with precursors of ethylsilicate(TEOS)and vinyltriethoxysilane(KH151), and which then was further doped with 1.5×10-3mol/L Ce(NO3)3to get a Ce-doped hybrid sol. A coating of this Ce-doped hybrid sol was prepared on aluminum tube by dipping method. Results of bluestone drips test, neutral salt spray test and electrochemical measurement showed that the coating doping modified hybrid film possessed superior corrosion performance rather than the conventional chromate passivation film. The infrared spectrum of the coating revealed that there existed different types of Si—O—Si covalent bonds and organic functional groups C=C covalent bonds, which might enhance the hydrophobicity of the coating. Finally SEM examination showed that the formed coating was dense, uniform and smooth.

铝管掺杂改性杂化膜的制备及其腐蚀性能

以硅酸乙酯(TEOS)和乙烯基三乙基氧基硅烷(KH151)为前驱体，采用溶胶-凝胶法制备了掺杂铈的杂化溶胶，再以1.5×10-3mol/L的Ce(NO3)3掺杂得到掺铈的杂化溶胶，并用浸渍法在铝管上涂覆该掺杂铈的杂化溶胶。青石滴液试验、中性盐雾试验和电化学测试结果表明，涂层掺杂改性杂化膜具有优于常规铬酸盐钝化膜的腐蚀性能。涂层的红外光谱显示，涂层中存在不同类型的Si-O-Si共价键和有机官能团C=C共价键，这可能增强了涂层的疏水性。SEM检测表明，成形涂层致密、均匀、光滑。
