摘要： A coating suitable for use as protective oxide-forming coatings on Nb-based substrates, and particularly monolithic niobium-based alloys, exposed to high temperatures and oxidative environments. The coating contains aluminum, may further contain silicon, and optionally contains niobium, titanium, hafnium, and/or chromium, which in combination form one or more intermetallic phases that promote the formation of a slow-growing oxide scale. The intermetallic phases may be M(Al,Si)3, M5(Al,Si)3, and/or M3Si5Al2 where M is niobium, titanium, hafnium, and/or chromium.

摘要： Niobium silicide articles are described. They include a surface region enriched with at least about 25 atom % germanium, which can enhance the properties of the article. Methods for preparing these articles are described as well. According to one method, an article is formed from a niobium silicide composite material which contains a selected amount of germanium. The article is then heat-treated under conditions sufficient to increase the level of germanium in the surface region to at least about 25 atom %, based on the total composition of the surface region. In another embodiment, a germanium-containing material is applied over a niobium-silicide article, and then diffused into the surface region of the article by way of a heat treatment.

摘要： Coatings suitable for use as protective oxide-forming coatings on Nb-based substrates exposed to high temperatures and oxidative environments. The coatings contain chromium and/or molybdenum, preferably contains silicon, and optionally contains niobium, titanium, hafnium, iron, rhenium, tantalum, and/or tungsten, which in combination form multiple intermetallic phases, which in combination form one or more intermetallic phases that promote the formation of a slow-growing oxide scale. Depending on the particular coating composition, the intermetallic phases maybe: a silicon-modified Cr2Nb Laves phase and optionally a chromium solid solution phase, a CrNbSi intermetallic phase, and/or an M3Si intermetallic phase where M is niobium, titanium, and/or chromium; or M5Si3, MSi2 and/or M3Si2 where M is molybdenum, niobium, titanium, chromium, hafnium, iron, rhenium, tantalum, and/or tungsten.
