LB膜法制备Y2O3掺杂的CeO2超薄陶瓷膜的X光电子能谱(XPS)研究 总被引:1,自引:0,他引:1
利用LB膜技术发展了一种制备组分可控的超薄陶瓷膜的方法。以Ce,Y的β-二酮络合物作为表面离子,替代传统的亚相离子,制得混合LB膜。并将它作为前驱物成功制得了Y2O3掺杂的CeO2(YDC)超薄膜。XPS谱表明,膜中Ce与Y的含量比控制得很好。 相似文献

A joint analysis of the results of electrochemical studies and the evolution of the parameters of a sodium chloride solution
droplet in contact with the coating under test reveals the pattern of changes in the surface state which result from the electrochemical
reactions and adsorption-desorption processes at the coating/electrolyte interface. Features of the corrosion process are
studied on titanium samples with different protective layers on the surface: (1) a natural oxide, (2) a coating prepared via
plasma electrolytic oxidation (PEO coating), (3) a PEO coating with a hydrophobic layer, and (4) a PEO coating with a superhydrophobic
nanocomposite layer. The best protective properties in a chloride-containing electrolyte are exhibited by the superhydrophobic
nanocomposite coating. The mechanism of corrosion protection of this coating is formulated. 相似文献
