摘要:
This invention relates to erosion resistant coatings comprising at least 2 sublayer systems in which each sublayer system is separated from another by an interlayer, wherein (i) each sublayer system is the same or different and comprises at least 4 layers, (ii) said layers comprise alternating layers of a nitride-containing compound of stoichiometric composition and a nitride-containing compound of nonstoichiometric composition, (iii) each sublayer system has a thickness of greater than about 0.4 microns, and (iv) each interlayer is the same or different and comprises a metal-containing compound. This invention also relates to a method for producing the coatings and to articles, e.g., gas turbine compressor rotor blade and stator vanes, coated with the coatings.
