| 摘 要： | 采用溶胶-凝胶法，以甲基三乙氧基硅烷(MTEOS)和正硅酸乙酯(TEOS)为原料，用浸渍-提拉法，在LY12铝合金基体表面成功制备了有机-无机杂化涂层.涂层表面光滑、平整、致密、无裂纹.通过液态浸渍实验、盐雾腐蚀实验和电化学腐蚀实验研究了有机-无机杂化涂层的耐腐蚀性能.结果表明，有机-无机杂化涂层耐腐蚀性能优良，具有很大的应用前景，使此杂化膜替代对环境有害的铬酸盐转化膜成为可能.

| Abstract: | Organic-inorganic hybrid coatings are prepared by sol-gel process,using methyltriethoxy silane(MTEOS) and tetraethoxy silane(TEOS) precursors.The as-prepared hybrid coatings were dense,uniform and defect-free.The corrosion resistance of the hybrid coatings applied on aluminum alloys is particular tested.The coatings show excellent corrosion resistant properties.So the new hybrid chromate-free coating systems can provide long-term and environmental friendly corrosion protection,in the contrast,the traditional chromate-based conversion coatings are toxic and suspicious of carcinogenic danger. |

| Keywords: | organic-inorganic hybrid coatings corrosion resistance |
