Study on High Temperature Corrosion Performance and Protective Coatings of Mo-containing Intermetallic Alloy IC6

摘要

Oxidation and hot corrosion behaviors of Ni₃Al-Mo （IC6） alloy were studied. Surface protective coatings were also developed for the engineering application of the alloy. The sputtered NiCrAlY coating may greatly improve the oxidation and hot corrosion resistance of IC6 alloy by forming a protective Al₂O₃ scale, and the coating shows little effect on the mechanical properties of IC6 alloy.
