A system and method are provided including an inclusion module to receive a powder sample from a powder source; a computed tomography equipment; a memory for storing program instructions; an inclusion processor, coupled to the memory, and in communication with the inclusion module, and operative to execute program instructions to: receive the powder sample; execute a computed tomography (CT) scan process of the received sample to generate a first dataset including one or more images; identify inclusions in the one or more images, via a segmentation process; reconstruct, via a reconstruction process, the identified inclusion into a 3D representation; measure the identified inclusion; mark the inclusions on one or more image slices from the 3D representations; and determine whether the powder source is contaminated based on the one or more marked images. Numerous other aspects are provided.

Alloy powder cleanliness inspection using computed tomography

A coating precursor slurry is provided, along with its methods of formation and use. The coating precursor slurry may include an organic binder comprising a polymeric component and a hardening reagent; an inorganic binder comprising an aluminum-nitrogen compound, a barium-containing organic compound, a nickel-containing organic compound, an ammonia polyphosphate, and phosphorus pentoxide; active components comprising Mo, Te, and graphite; and a solvent.

High temperature dry film lubricant

A modified alloy is disclosed including a base alloy composition and an additive gamma prime antioxidant. The base alloy composition includes a concentration of a gamma prime antioxidant less than an effective concentration of the gamma prime antioxidant. The additive gamma prime antioxidant is intermixed with the base alloy composition to form the modified alloy, preferentially segregating to a gamma prime phase of the modified alloy and increasing the concentration of the gamma prime antioxidant to be at least the effective concentration of the gamma prime antioxidant. The effective concentration imparts reduced oxidation susceptibility of the gamma prime phase. An article is disclosed including the modified alloy. A coated article is disclosed including a coating disposed on a surface of an article having the base alloy composition. The coated article includes a reduced stress accelerated gamma prime oxidation static crack growth susceptibility in comparison with the base alloy composition.

Modified articles, coated articles, and modified alloys

Disclosed herein is a system including a motor comprising a rotor, a stator and a sealing assembly having at least one joint and a monolithic ceramic separator. Each joint of the sealing assembly is a chemical bond joint, and the monolithic ceramic separator is disposed in a gap between the rotor and the stator of the motor such that the sealing assembly hermetically isolates the rotor and the stator.

Hermetic sealing assembly and electrical device including the same

A coating for use in combustion systems includes a plurality of refractory metal particles in a ceramic, glass or metal matrix disposed on surfaces of the system that are prone to slag, ash, and/or char buildup during operation of the combustion system. The coating is effective to prevent any substantial interaction with the slag, ash, and/or char.

Anti-fouling coatings for combustion system components exposed to slag, ash and/or char

Disclosed herein is a component in a combustion system comprising a composite, the composite comprising silicon carbide; and a refractory metal silicide comprising a phase selected from RmSi, RmSiC, RmSi, and a combination thereof; wherein Rm is a refractory metal selected from molybdenum, tungsten, and a combination thereof. Also disclosed is a process for preventing slag, ash, and char buildup on a surface, comprising disposing a first surface of the composite on the surface; replacing a component comprising the surface with a component consisting of the composite; or a combination thereof.

A method for mitigating stress corrosion cracking of a component exposed to a high temperature water in a high temperature water system is provided. The method comprises the steps of lowering corrosion potential conditions to a desired low corrosion potential in the high temperature water environment; and introducing a first material comprising zinc into the high temperature water environment, such that the desired low corrosion potential facilitates transport of the first material into cracks in a structure communicative with the high temperature water environment.
