摘要：

Cathodic electrodeposition of CeO2 and Ce1-xGdxO2-y was performed from aqueous and mixed ethyl alcohol-water solutions of CeCl3 and GdCl3 on Ni foil and Ni-yttria stabilized zirconia substrates. The influence of hydrogen peroxide on the electrodeposition process was studied. Electrochemical intercalation of poly(diallyldimethylammonium chloride) into the deposits was demonstrated and the mechanism of intercalation is discussed. The experimental results indicate that the polymer acts as a binder, providing better adhesion of the organoceramic deposits and reducing cracking while allowing for film formation on porous substrates. The deposits were studied by X-ray diffraction, thermogravimetric analysis and scanning electron microscopy. (C) 2001 Elsevier Science Ltd and Techna S.r.l. All rights reserved.
