Abstract
A nanostructured CeO2–Ni coating is prepared on a steel substrate via two-step electrodeposition. An oxide scale with a multi-layer structure of Cr2O3–(Mn,Cr)3O4–(Ni,Mn,Cr)3O4–NiO has developed on the coated steel after 1680 h of oxidation in air at 800 °C. CeO2 is uniformly distributed in the spinel and NiO layers. The synergistic effects originating from nanostructured CeO2 and NiO not only reduce the growth rate of Cr2O3 and suppress the outward diffusion of Cr, but also improve the electrical performance of the surface scale.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
