摘要:
A method includes applying a coating precursor material over a substrate, the coating precursor material comprising a powder having an average particle diameter in a range of about 10 nanometers to about 10 microns comprising a fluoride eutectic, a metal capable of oxidizing at about 535° C. to about 800° C., one or more materials selected from the group consisting of a metal oxide, a glass, a carbide, and a nitride, and optionally, a precious metal selected from silver, palladium, platinum, gold, rhodium, and alloys thereof, subjecting the coating to a sintering heat treatment, occurring at a first temperature in an inert or reducing atmosphere to sinter the metal of the precursor material, and exposing the coating to an oxidizing heat treatment performed in an oxidizing atmosphere at a second temperature that is less than the first temperature to oxidize a portion of the metal in the coating precursor material.
