Abstract
The yttria-stabilized zirconia (YSZ) coatings with 4–6 mol.% Y2O3 content were irradiated by 6 MeV Au ions with a fluence 6.0 1015 ions/cm2. The cubic to monoclinic transformation of ZrO2 was identified in the Au-irradiated samples. The cavities were observed in the YSZ layer, while larger size cavities were found inside the 6YSZ layer. LBE corrosion results showed that irradiation improved the adhesion and corrosion resistance of the coating due to the fact that irradiation released the stresses in the coating. Overall, the 4YSZ coating showed the best corrosion resistance and irradiation resistance in the case of heavy ion irradiation.
期刊介绍:
Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
