A series of aluminum phosphate ceramic coating with the entrapped ceria (CeO₂) nanoparticles, which is denoted APC, were constructed by steam-assisted curing method on cast Al-10Si alloy. The composition, structure and morphology of the coatings were investigated using FT-IR, XRD, XPS and SEM. Moreover, the corrosion properties of coatings were evaluated by the electrochemical tests. All the coatings were demonstrated to be homogeneous, compact on the substrate surface. The appropriate amount of CeO₂ can effectively improve the corrosion resistance and durability of the coating. In addition, the formation and corrosion resistance mechanism of the coatings were studied in this work.

在铸造的Al-10Si合金上，通过蒸汽辅助固化法制备了一系列包覆有二氧化铈（CeO ₂）纳米粒子的磷酸铝陶瓷涂层，称为APC。用FT-IR，XRD，XPS和SEM研究了涂层的组成，结构和形貌。此外，通过电化学测试评估了涂层的腐蚀性能。已证明所有涂层在基材表面上均一，致密。适量的CeO ₂可以有效地改善涂层的耐腐蚀性和耐久性。此外，在这项工作中研究了涂层的形成和抗腐蚀机理。
