摘要

对 Y2O3 含量为 4-6 mol.% 的钇稳定氧化锆 (YSZ) 镀层进行了 6 MeV 金离子照射，离子流为 6.0 × 1015 离子/cm2。在金辐照样品中发现了 ZrO2 从立方到单斜的转变。在 YSZ 层中观察到了空穴，而在 6YSZ 层中发现了较大尺寸的空穴。LBE 腐蚀结果表明，由于辐照释放了涂层中的应力，辐照提高了涂层的附着力和耐腐蚀性。总体而言，在重离子辐照情况下，4YSZ 涂层的耐腐蚀性和耐辐照性最好。

Heavy-ion-irradiation effect of yttrium-stabilized-zirconia coatings on microstructure and lead-bismuth corrosion

The yttria-stabilized zirconia (YSZ) coatings with 4–6 mol.% Y₂O₃ content were irradiated by 6 MeV Au ions with a fluence 6.0

\times

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.
