Abstract

This work aimed to investigate the corrosion behavior of Si-18at%Y alloys in air oxidation and water-oxygen corrosion environments. The objective was to understand how different times, temperatures, and the presence or absence of water vapor affected the distribution and transformation of the alloy's phases. The results revealed that extended duration facilitates growth of yttrium silicate, while higher temperature promotes stable phase transformation. The distribution and type of yttrium silicate are influenced by the presence of SiO₂. At lower temperatures, water vapor facilitated the formation of SiO₂, whereas at higher temperatures, it depleted SiO₂ and inhibited the generation of yttrium silicate.
