Preparation and structure characterization of CeO2 films on stainless steel substrates deposited by laser ablation with Ar+ ion beam assistance

摘要

The CeO$-2$/ films were deposited by pulsed laser ablation on stainless steel substrates at room temperature with the Ar$+$PLU$/ ion beam assistance. The results show that when the CeO$-2$/ films were deposited directly on the stainless steel substrates, the desired (001)-normal textured were achieved, but there was no evidence for alignment of in- plane crystal axes. Further experimental results indicate that CeO$-2$//YSZ (Yttria-Stabilized Zirconia)/stainless steel films deposited under the same conditions are not only normal orientation to the substrate's surface but also highly in-plane textured.
