TiFeN3

TiFeN3 is an interstitial nitride compound combining titanium, iron, and nitrogen, belonging to the family of transition metal nitrides that exhibit high hardness and thermal stability. This material is primarily of research interest for wear-resistant coatings and high-temperature applications where combined hardness and toughness are beneficial; it represents an experimental composition within the broader titanium–iron–nitrogen system rather than an established commercial alloy, and engineers would evaluate it as an alternative to conventional TiN or CrN coatings when iron-modified nitride properties prove advantageous for specific tribological or structural demands.
