Thermal-barrier coating

Abstract

Thermal-barrier coatings for protecting a substrate from heat include a nitride layer, with the nitride layer including an interstitial nitride of a transition metal. In some embodiments, the nitride layer may include, for example, titanium nitride, niobium nitride, hafnium nitride, vanadium nitride, or zirconium nitride. The implementations further include a method comprising providing a substrate for use in assembling structures (e.g., a turbine blade) configured to be exposed to high temperature conditions, and applying a coating to the substrate, with the coating comprising a nitride layer, and with the nitride layer comprising transition-metal nitride.
