Ti4 N2

Ti₄N₂ is a titanium nitride compound that belongs to the class of transition metal nitride semiconductors, combining titanium's desirable properties with nitrogen's hardening effects. This material is primarily of research interest for hard coatings, wear-resistant surfaces, and potential optoelectronic applications, where its ceramic-like hardness and electrical properties offer advantages over pure titanium or conventional nitride films in extreme wear or high-temperature environments.
