摘要： Chromium is deposited on a surface using a coating tape having a source layer including a powdered source of chromium, a solid reactant that reacts with solid chromium at elevated temperature to produce a gaseous chromium-containing compound, an inert powder dispersed with the powdered source of chromium, and a binder. Preferably, a porous media layer including a porous media material and a binder is affixed to the source layer. The coating tape is positioned adjacent to the surface of the substrate, with the porous media layer, where present, in contact with the surface. The coating tape and substrate are placed into a container, and the container is heated to elevated temperature in a non-oxidizing atmosphere. The gaseous chromium-containing compound is produced and chromium is deposited from the gaseous chromium-containing compound onto the surface of the substrate.

摘要： A single-crystal article having a thermal barrier coating on a surface thereof, and a method for processing the article so as to promote the life of the coating. As a result of its single-crystal microstructure, the article is characterized by having been unidirectionally solidified along a primary crystallographic direction, and secondary crystallographic directions that are normal to the primary crystallographic direction. Improved spallation resistance of the coating is achieved by selectively orienting the secondary crystallographic direction with respect to a direction normal to a life-limiting surface region of the thermal barrier coating.

摘要： A method and apparatus for forming a multilayer thermal barrier coating such that the coating is composed of substantially homogeneous layers of different ceramic materials. The method entails supporting an article within a coating apparatus and in proximity to ceramic ingots of the different ceramic materials, and then simultaneously directing electron beams at both ingots so as to maintain a portion of each ingot in a molten state. According to a particular aspect of this invention, vapors of both ceramic materials coexist within the coating apparatus, yet each ceramic material is sequentially deposited onto the article by sequentially interrupting exposure of surfaces of the article to the vapors, such that the vapors form homogeneous successive layers on the surface. Exposure of the article to one or more of the vapors can be interrupted with a baffle, such that the vapor of only one of the ceramic ingots is directly deposited on a given surface of the article at any instant. The baffle can be employed in conjunction with the article being rotated at a constant or variable speed, and/or being translated above the members within the vessel to alter the relative thicknesses of the ceramic and an intermediate layer that is formed between adjacent layers and is composed of a mixture of the ceramic materials.

摘要： A thermal barrier coating adapted to be formed on an article subjected to a hostile thermal environment while subjected to erosion by particles and debris, as is the case with turbine, combustor and augmentor components of a gas turbine engine. The thermal barrier coating is composed of a metallic bond layer deposited on the surface of the article, a ceramic layer overlaying the bond layer, and an erosion-resistant composition dispersed within or overlaying the ceramic layer. The bond layer serves to tenaciously adhere the thermal insulating ceramic layer to the article, while the erosion-resistant composition renders the ceramic layer more resistant to erosion. The erosion-resistant composition is either alumina (Al.sub.2 O.sub.3) or silicon carbide (SiC), while a preferred ceramic layer is yttria-stabilized zirconia (YSZ) deposited by a physical vapor deposition technique to have a columnar grain structure.

摘要： A coated article is prepared by furnishing an article substrate having a free sulfur content of less than about 1 part per million. The low-sulfur article may be made of a material selected to have a low sulfur content, provided with a scavenging element that reacts with free sulfur to produce a sulfur compound, or desulfurized by contact with a reducing gas such as hydrogen. A platinum-group metal layer is deposited over the article substrate, and a ceramic coating is applied over the platinum-group metal layer.

摘要： A thermal barrier coating and a method for forming the coating on an article designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method is particularly directed to increasing the spallation resistance of a thermal barrier coating system that includes a thermal insulating ceramic layer. The coating system of this invention generally includes a nickel aluminide alloy on which an aluminum oxide layer is formed, over which a ceramic layer is deposited so as to overlie and contact the aluminum oxide layer. The coating system does not include a bond coat, such as a diffusion aluminide or MCrAlY coating known in the prior art. The nickel aluminide alloy may be a binary NiAl alloy consisting essentially of nickel and aluminum in stoichiometric amounts, or may contain one or more oxygen-active elements. The NiAl alloy may be provided as a monolithic layer on a superalloy, or may be the base material for the article on which the thermal barrier coating is formed.

摘要： A bond-coated substrate is protected with an alpha alumina layer. The alpha alumina layer may be deposited as a relatively thick layer directly onto the bond-coated substrate. In this embodiment, no further ceramic layer overlies the alpha alumina layer. Other ceramics may be mixed into the alpha alumina layer, however. In another embodiment, a layer of a ceramic other than alpha alumina is deposited over the bond-coated substrate, and an alpha alumina layer is deposited over the ceramic layer.

摘要： A method for recovering Pt from Pt-bearing coating on a gas turbine engine component. The component is contacted with a chemical stripping agent to dissolve away constituents of the coating and produce a Pt-bearing film of acid oxidation products at the surface of the component. The film is removed from the component to produce a Pt-rich residue containing at least about 10% Pt. The Pt-rich residue is collected and refined to recover Pt therefrom.

摘要： A method of removing hot corrosion products from the surface of a component exposed to corrosive conditions at elevated temperatures, as is the case with turbine, combustor or augmentor components of gas turbine engines. The method is particularly suited for the removal of hot corrosion products from components protected with a diffusion aluminide coating, either as an environmental coating or as a bond coat for a thermal barrier coating (TBC). The processing steps of the method include immersing the component in a heated liquid solution containing acetic acid, and then agitating the surfaces of the component while the component remains immersed in the solution. In this manner, hot corrosion products on the surfaces of the component are removed without damaging or removing the diffusion aluminide coating. As a result, regions of the component from which the hot corrosion products were removed can then be repaired by a suitable aluminizing process.
