In this study, the compact and uniform CrSi (Cr_0.92Si_0.08, Cr_0.85Si_0.15, Cr_0.65Si_0.35) coatings have been deposited on zircaloy-4 substrates by magnetron sputtering technique, and their oxidation performances in steam environment have been investigated at 1200°C for 60 min. Microstructures and phase compositions of coatings before and after oxidation indicate that CrSi coatings exhibit protective behavior. The dense Cr₂O₃ oxide layer on CrSi coatings can significantly improve the oxidation resistance, and their weight gains are reduced. The Cr_0.92Si_0.08 coating shows the optimum performance due to the integrality and protectiveness of the Cr₂O₃ oxide layer.

在这项研究中，通过磁控溅射技术在 zircaloy-4 基体上沉积了致密均匀的 CrSi（Cr _0.92 Si _0.08，Cr _0.85 Si _0.15，Cr _0.65 Si _0.35）涂层，并研究了它们在蒸汽环境中的氧化性能1200°C 60 分钟。氧化前后涂层的微观结构和相组成表明 CrSi 涂层表现出保护行为。CrSi涂层上致密的Cr ₂ O ₃氧化层可显着提高抗氧化性，并减少其增重。Cr _0.92 Si _0.08由于 Cr ₂ O ₃氧化物层的完整性和保护性，涂层显示出最佳性能。
