Co9 Y3
metal· Co9 Y3
Co9Y3 is a cobalt-yttrium intermetallic compound belonging to the family of rare-earth-modified cobalt alloys. This material is primarily investigated in research contexts for high-temperature applications where oxidation resistance and thermal stability are critical, leveraging yttrium's known ability to improve oxide scale adhesion and reduce oxygen diffusion in cobalt-based systems. Industrial interest focuses on aerospace coatings, superalloy matrices, and advanced thermal barrier applications where conventional cobalt alloys face degradation at elevated temperatures.
