摘要：

A new electrochemical method using a non-aqueous electrolyte was utilized for deposition of cerium oxide layers on different substrates. X-Ray photoelectron spectroscopy was used to examine the nature of cathodically deposited cerium thin films on stainless steel (SS), ZrO2/SS and Al2O3/SS substrates as a function of the preparation conditions and thermal treatment. It was established that in the case of a naturally aerated solution, Ce2O3 was formed during the process of electrolysis by the oxygen present in the electrolyte whereas in a deaerated medium cerium was deposited in the metal state being oxidized to a CeO2 upon exposure to air. Due to the thermal treatment, mixing of the deposited cerium oxide layer with ZrO2 and Al2O3 films was observed. (C) 2003 Elsevier B.V. All rights reserved.
