Abstract

This study aimed to reveal the corrosion behavior of Al-CeO₂ composites. Samples were fabricated with 1 and 10 wt% reinforcement ratios, respectively. In-situ phases like complex oxide and intermetallic were observed at higher CeO₂ content. The corrosion behavior of samples was significantly developed with CeO₂ and in-situ oxides. Particularly, the corrosion rate was reduced by CeO₂ particles. Furthermore, usage of 10 wt% CeO₂ increased the charge transfer resistance to 1467.02 Ω. It can be stated that CeO₂ particles and in-situ oxides were favorable for enhanced corrosion behavior.

调整热压铝- ceo2复合材料的腐蚀行为

本研究旨在揭示Al-CeO2复合材料的腐蚀行为。样品分别以1 wt%和10 wt%的增强率制备。在较高的CeO2含量下，可以观察到复合氧化物和金属间化合物等原位相。CeO2和原位氧化物显著改善了样品的腐蚀行为。CeO2颗粒明显降低了腐蚀速率。此外，使用10 wt%的CeO2将电荷转移电阻提高到1467.02 Ω。CeO2颗粒和原位氧化物有利于增强腐蚀行为。
