Abstract: Engine components that include a compacted powder material comprising a nickel-based superalloy having less than five parts per million sulfur, by weight and methods of forming the components are provided. In an embodiment, by way of example only, a method includes flowing a gas into a can with a metal powder therein, the gas comprising hydrogen, the can configured to be used for a consolidation process, and the superalloy comprising sulfur. Gas is flowed into and then removed from the can. A sulfur content of the removed gas is determined during the process. The can and the metal powder therein are subjected to the consolidation process, if a determination is made that the sulfur content of the metal powder is below a threshold value, the threshold value being a value below about 1 part per million by weight.

Abstract: A durable protective coating may be formed by applying a thin layer of metastable alumina to a bond coating on a substrate. A thermal barrier coating may then be applied to the metastable alumina and the resulting part may be heat treated to transform the metastable alumina to a mixed alpha alumina having particles of the thermal barrier coating, such as zirconia in the case of an yttria stabilized zirconia thermal barrier coating, dispersed therein. The resulting thermal barrier coating may inhibit microbuckling of the thermally grown oxide scale that grows over time at the thermal barrier coating-bond coating interface.

Abstract: A turbine engine component includes an electron beam-physical vapor deposition thermal barrier coating covering at least a portion of a substrate. The thermal barrier coating includes an inner layer having a columnar-grained microstructure with inter-columnar gap porosity. The inner layer includes a stabilized ceramic material. The thermal barrier coating also includes a substantially non-porous outer layer, covering the inner layer and including the stabilized ceramic material. The outer layer is deposited with continuous line-of-sight exposure to the vapor source under oxygen deficient conditions. The outer layer may further comprise a dopant oxide that is more readily reducible than the stabilized ceramic material. During deposition, the outer layer may also have an oxygen deficient stoichiometry with respect to the inner layer. Oxygen stoichiometry in the outer layer may be restored by exposure of the coated component to an oxidizing environment.

Abstract: A component for a turbine engine component includes a ceramic substrate having a surface, an environmental barrier layer bonded to the substrate surface, and an impact-resistance layer bonded to the environmental barrier layer, the impact-resistance layer having a melting point higher than about 2700° F., and further having a between about 10 and about 30% porosity. The impact-resistance layer, environmental barrier layer, and interfaces at which the environmental layer is bound to the substrate surface and the impact-resistance layer are more readily shearable than the substrate. A method for protecting a turbine engine component from environmental and particle impact-related damage includes the steps of coating a substrate surface with the environmental barrier layer, and coating the environmental barrier layer with the impact-resistance layer.
