Oxidation and degradation of Cr-coated Zr-based alloy up to 1500°C: Effect of Cr thickness

Key Points

• Oxidation significantly affects the thermal stability of chromium-coated zirconium alloys at temperatures up to 1500°C.
• A critical threshold in Cr coating thickness influences degradation rates, with thinner coatings showing increased oxidation.
• Analysis of the oxidation and degradation behavior involved high-temperature exposure assessments on zirconium-based alloys.
• These findings highlight the importance of coating thickness in maintaining alloy integrity in high-temperature environments.
