Abstract

The pack cementation method was applied for the preparation of four coatings. The pack mixtures consisting of Zn, Y₂O₃, and NH₄Cl were used in this work. The impact of adding Y₂O₃ on the appearance, the components, and the anti-corrosion action of coatings was analyzed. The appearance was observed by scanning electron microscope. The components were characterized by X-ray diffraction. The results suggested that adding Y₂O₃ increased the coatings thickness and perfected the coatings quality. Without adding Y₂O₃, the coatings obtained consisted of Zn atoms and a few Fe atoms. Minute amounts of Y atoms were detected in the coatings at adding Y₂O₃. The impact of adding Y₂O₃ on the corrosion performance of coatings was assessed by the corrosion morphology analysis and an electrochemical test. The results showed that adding Y₂O₃ increased anti-corrosion ability. When the additive amount of Y₂O₃ was 4 wt %, the coatings exhibited the largest thickness and the strongest anti-corrosion ability.

添加Y2O3对充填法镀锌层性能的影响

摘要

四种涂层的制备均采用包胶法。在这项工作中使用了由 Zn、Y ₂ O ₃和 NH ₄ Cl组成的填充混合物。_{分析了添加Y 2} O ₃对涂层外观、成分及防腐作用的影响。通过扫描电子显微镜观察外观。这些组分通过 X 射线衍射进行表征。结果表明，添加Y ₂ O ₃增加了涂层厚度并改善了涂层质量。不加Y ₂ O ₃，获得的涂层由 Zn 原子和少量 Fe 原子组成。_{在添加 Y 2} O ₃时在涂层中检测到微量的 Y 原子。通过腐蚀形貌分析和电化学测试评估添加Y ₂ O ₃对涂层腐蚀性能的影响。结果表明，添加Y ₂ O ₃提高了抗腐蚀能力。_{当Y 2} O ₃添加量为4 wt%时，涂层表现出最大的厚度和最强的防腐能力。
