    • 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.
    • 一种方法包括将涂层前体材料涂覆在基底上,所述涂层前体材料包含平均粒径在约10纳米至约10微米范围内的粉末,其包含氟化物共晶体,能够在约535℃下氧化的金属 至约800℃,选自金属氧化物,玻璃,碳化物和氮化物的一种或多种材料,以及任选的选自银,钯,铂,金,铑, 及其合金,对涂层进行烧结热处理,在惰性或还原性气氛中的第一温度下进行烧结,烧结前体材料的金属,并在第二次氧化气氛中进行氧化热处理 温度小于第一温度以氧化涂层前体材料中的一部分金属。
