摘要： 采用锆化工艺在铝板表面制备了陶瓷膜,用扫描电镜和能谱仪分析了陶瓷膜的组织形貌和元素成分,用电化学法研究了陶瓷膜的耐蚀性能,用附着力测定仪测试了陶瓷膜的涂装附着力性能以及用中性盐雾实验研究了涂层体系的耐盐雾性能.结果表明:铝板表面的陶瓷膜为无色的纳米膜层,主要由Zr,Si和Al的氧化物组成;锆化陶瓷膜的耐电化学腐蚀性能优异,与环氧树脂漆或聚氨酯漆的附着力均为1级;整个涂层体系可通过600 h的中性盐雾实验.锆化陶瓷膜可以用作铝板的漆前打底膜,有望替代污染较重的磷化处理工艺.

Abstract: The zirconia ceramic film was deposited on aluminum sheets via fluorozirconate treatment. The morphology and composition of the ceramic film were investigated by scanning electron microscopy and energy dispersive spectrometer, and its corrosion resistance was tested electrochemically. Moreover, the adhesion and salt spray resistance of the ceramic films and substrate were investigated via adhesion test and neutral salt spray test, respectively. The results showed that the ceramic film is nanofilm and colorless and consists mainly of the Zr, Si and Al oxides. The resistance to electrochemical corrosion of the film is high, and its adhesion to the epoxy resin paints or polyurethane paints is of the Grade I. Both the film and substrate have passed 600 h salt spray test. So, the zirconia ceramic film can be used as the backing film on aluminum sheets surface for subsequent painting, and it is expected to be the pretreatment process instead of the heavily-pollutive phosphorization technology.
