摘要： A method of introducing small amounts of a refractory element into a vapor deposition coating. A second material (30), containing at least two elements which are desired to be deposited as a coating on a base material, has placed over it a first material (20) substantially comprising such two elements and a refractory element. The first material (20) is adapted to permit transport of the at least two elements in the second material (30) through the first material (20) when the first (20) and second (30) material are in a molten state and in touching contact with the other so as to permit evaporation of the two elements and the refractory element from an exposed surface. Heat is supplied to the first (20) and second (30) materials to permit evaporation of the at least two elements of second material (30) and the refractory element in the first material (20), and the resulting vapors are condensed as a deposit on a base material (50). A particular method of heating is further disclosed to assist in maintaining adequate rates of evaporation for the aforesaid method, wherein the supplied heat is supplied to an inner heated area (91) and a surrounding outer heated area (92) and at least a portion of the inner heated area (91) is heated to a greater temperature than the outer heated area (92).

摘要： A protected article includes a nickel-base superalloy substrate, an interlayer overlying the substrate, and a protective layer overlying the interlayer. The protective layer has a composition comprising at least one of rhodium, platinum, palladium, and ruthenium. In one composition, palladium is present in an amount of from about 1 to about 41 atomic percent; platinum is present in an amount of about (40+atomic percent palladium) atomic percent for palladium ranging from about 1 atomic percent to about 14 atomic percent and up to about 54 atomic percent for palladium ranging from about 15 atomic percent up to about 41 atomic percent; rhodium is present in an amount of at least about 24 atomic percent; zirconium, hafnium, titanium, and mixtures thereof are present in an amount of from zero up to about 5 atomic percent; and ruthenium is present in an amount of from zero up to about 5 atomic percent, balance impurities. The interlayer has a coefficient of thermal expansion intermediate between that of the substrate and that of the protective layer. The protected article is fabricated by furnishing the substrate, applying the interlayer over the substrate, and applying the protective layer over the interlayer.

摘要： A barrier coating is disclosed, containing about 15 atom % to about 95 atom % chromium; and about 5 atom % to about 60 atom % of at least one of rhenium, tungsten, and ruthenium. Nickel, cobalt, iron, and aluminum may also be present. The barrier coating can be disposed between a metal substrate (e.g., a superalloy) and an oxidation-resistant coating, preventing the substantial diffusion of various elements at elevated service temperatures. A ceramic overcoat (e.g., based on zirconia) can be applied over the oxidation-resistant coating. Related methods for applying protective coatings to metal substrates are also described.
