Ti2AlN
metal· Ti2AlN
Ti2AlN is a ternary ceramic compound belonging to the MAX phases (metal-aluminum-nitride family), which are layered nanolaminate materials combining metallic and ceramic characteristics. This material exhibits high hardness and stiffness while maintaining some damage tolerance through its layered crystalline structure, making it attractive for applications requiring wear and thermal resistance. Ti2AlN is primarily investigated in research and emerging industrial contexts for protective coatings and high-temperature structural applications where conventional ceramics would be too brittle or where metallic alternatives lack sufficient hardness.
