Ti3N4

Ti3N4 is a titanium nitride ceramic compound that belongs to the family of refractory metal nitrides, offering high hardness and thermal stability at elevated temperatures. This material is primarily of research and advanced manufacturing interest, particularly in cutting tool coatings, wear-resistant surfaces, and high-temperature structural applications where conventional titanium alloys reach their limits. Engineers select titanium nitrides over softer alternatives when extreme hardness, oxidation resistance, and thermal durability are critical—though Ti3N4 remains less commercially established than binary TiN, making it most relevant to cutting-edge aerospace, automotive, and tooling development programs.
