C22C 27/02
US Classification:
428632, 428472, 428641, 428651, 428660, 428662
Abstract:
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), M(Al,Si), and/or MSiAlwhere M is niobium, titanium, hafnium, and/or chromium.

US Classification:
428632, 428472, 428641, 428651, 428660, 428662
Abstract:
Nb—Si based alloy articles comprising a Nb—Si based alloy upon which is disposed an environmentally-resistant coating are described. They include a coating comprising at least one phase selected from the group consisting of M(Al,Si), M(Al,Si), and MSiAl, wherein M is one or more of Nb, Ti, Hf, Cr. Such coating can improve the environmental (e. g. , in oxidation-promoting environments) resistance of a Nb—Si based alloy and alloy articles. Methods for preparing these articles are described as well.

US Classification:
428662, 420428, 420588, 416241 R, 416241 B, 428469, 428472
Abstract:
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 may be: a silicon-modified CrNb Laves phase and optionally a chromium solid solution phase, a CrNbSi intermetallic phase, and/or an MSi intermetallic phase where M is niobium, titanium, and/or chromium; or MSi, MSiand/or MSiwhere M is molybdenum, niobium, titanium, chromium, hafnium, iron, rhenium, tantalum, and/or tungsten.
Niobium-Silicide Alloys Having A Surface Region Of Enhanced Environmental-Resistance, And Related Articles And Processes
US Patent:
2008014, Jun 19, 2008
Filed:
Dec 19, 2006
Appl. No.:
11/612743

C22C 27/02
C22C 27/02
US Classification:
148243, 148422, 148281
Abstract:
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.
