    摘要： A thermal barrier coating and deposition process for a component intended for use in a hostile thermal environment, such as the turbine, combustor and augmentor components of a gas turbine engine. The TBC has a first coating portion on at least a first surface portion of the component. The first coating portion is formed of a ceramic material to have at least an inner region, at least an outer region overlying the inner region, and a columnar microstructure whereby the inner and outer regions comprise columns of the ceramic material. The columns of the inner region are more closely spaced than the columns of the outer region so that the inner region of the first coating portion is denser than the outer region of the first coating portion, wherein the higher density of the inner region promotes the impact resistance of the first coating portion.

    摘要： A reduced thermal conductivity thermal barrier coating having improved impact resistance for an underlying substrate of articles that operate at, or are exposed to, high temperatures. This coating comprises an inner high fracture toughness layer nearest to the underlying substrate and having a thickness up to about 5 mils (127 microns) sufficient to impart impact resistance to the thermal barrier coating, and comprises a zirconia-containing ceramic composition having a c/a ratio of the zirconia lattice in the range of from about 1.011 to about 1.016 and stabilized in the tetragonal phase by a stabilizing amount of a stabilizing metal oxide selected from the group consisting of yttria, calcia, ceria, scandia, magnesia, india, lanthana, gadolinia, neodymia, samaria, dysprosia, erbia, ytterbia, europia, praseodymia, and mixtures thereof. The thermal barrier coating further includes an outer thermal insulating layer adjacent to and overlaying the inner layer and comprising a ceramic thermal barrier coating material. The thermal barrier can be used to provide a thermally protected article having a substrate (e.g., metal substrate) and optionally a bond coat layer adjacent to and overlaying the substrate. The thermal barrier coating can be prepared by forming the inner high fracture toughness layer, followed by forming on the inner layer the outer thermal insulating layer.

    摘要： A beta-phase nickel aluminide (NiAl) overlay coating (24) and method for modifying the grain structure of the coating (24) to improve its oxidation resistance. The coating (24) is deposited by a method that produces a grain structure characterized by grain boundaries (44) exposed at the outer coating surface (36). The grain boundaries (44) may also contain precipitates (40) as a result of the alloyed chemistry of the coating (24). During or after deposition, the overlay coating (24) is caused to form new grain boundaries (34) that, though open to the outer surface (36) of the coating (24), are free of precipitates or contain fewer precipitates (40) than the as-deposited grain boundaries (44). New grain boundaries (34) are preferably produced by causing the overlay coating (24) to recrystallize during coating deposition or after deposition as a result of a surface treatment followed by heat treatment.

    摘要： A process for depositing a ceramic coating on a component. The process involves a technique for evaporating an evaporation source containing multiple different oxide compounds, at least one of the oxide compounds having a vapor pressure that is higher than the remaining oxide compounds, to deposit a coating of the multiple oxide compounds. A high energy beam is projected onto the evaporation source to melt and form a vapor cloud of the oxide compounds of the evaporation source, while preventing the vapor cloud from contacting and condensing on the component during an initial phase in which the relative amount of the one oxide compound in the vapor cloud is greater than its relative amount in the evaporation source. During a subsequent phase in which the relative amount of the one oxide compound in the vapor cloud has decreased to something approximately equal to its relative amount in the evaporation source, the vapor cloud is allowed to contact and condense on the component to form the coating.

    摘要： An article protected by a thermal barrier coating system is fabricated by providing an article substrate having a substrate surface, and thereafter producing on the substrate surface a protective coating having a polished, pre-oxidized protective coating surface. The protective coating is produced by depositing the protective coating on the substrate surface, the protective coating having a protective coating surface, thereafter polishing the protective-coating surface, and thereafter controllably oxidizing the protective-coating surface. The protective-coating surface may optionally be controllably roughened by grit blasting after polishing and before controllably oxidizing. A thermal barrier coating may be deposited overlying the polished, pre-oxidized protective-coating surface.
