· JVASP-24635· Zr3AlN

Zr3AlN is a ternary intermetallic nitride compound combining zirconium, aluminum, and nitrogen, belonging to the family of refractory metal nitrides and MAX-phase-related materials. This is primarily a research and development material investigated for high-temperature structural applications, wear resistance, and potential thermal barrier or protective coating roles where conventional alloys reach their limits. Zr3AlN combines the hardness and refractory properties of metal nitrides with potential for improved fracture toughness compared to monolithic ceramics, making it of interest for aerospace and extreme-environment engineering where thermal stability and oxidation resistance are critical.
