FeNiN

FeNiN is an iron-nickel nitride intermetallic compound that combines iron and nickel with nitrogen to form a hard, dense metallic material. This material family is primarily investigated for applications requiring enhanced hardness and wear resistance, particularly in wear-resistant coatings, cutting tools, and specialized surface treatments where conventional steel or iron alloys fall short. FeNiN represents an emerging research compound in the broader field of transition metal nitrides, offering potential advantages in high-hardness applications and elevated-temperature stability compared to traditional ferrous alloys.
