溶胶-凝胶技术在铝合金表面处理中的研究进展

Research Progress in Sol-gel Technology Applied in the Surface Treatment for Aluminum Alloy

采用溶胶-凝胶(Sol-gel)方法可以在材料表面制备各种Sol-gel无机物膜层,以赋予材料新的使用性能。综述了溶胶-凝胶技术在铝和铝合金的表面涂层制备以及在铝合金阳极氧化膜封闭方面的应用现状,指出溶胶-凝胶技术在铝合金表面处理方面是又一重要的绿色环保、有效的新技术。

Various inorganic coatings can be prepared on the material surface by sol-gel technology so that the material can be endowed with new properties. The preparation of coatings and the application of sealing for anodized films on Al and Al alloy substrates by sol-gel method are reviewed in this paper. It is found that the sol-gel method is an effective and environmentally friendly technology for the surface treatment of Al and Al alloys.
