An intermediate solid oxide fuel cell (SOFC) stage and methods for inspecting an assembled portion of an SOFC are presented. One method for inspecting an assembled portion of an SOFC includes applying a pneumatic constraint to a fluid, where the fluid is in communication with the assembled portion of the SOFC, determining a quality control parameter of the assembled portion of the SOFC in response to the pneumatic constraint, and ascertaining health of the assembled portion of the SOFC based on the quality control parameter. The assembled portion of the SOFC includes a metallic interconnect, where the metallic interconnect includes a flow field.

A rare earth silicate-based hermetic layer includes a thermal sprayed coating including a rare earth silicate having a hermetic microstructure. An environmental barrier coating includes a bond coat layer including silicon; and at least one rare earth silicate-based hermetic layer deposited on the bond coat layer by thermal spraying. The rare earth silicate-based hermetic layer includes a thermal sprayed coating including a rare earth silicate having a hermetic microstructure. An article for service in extreme environments may be provided with such an environmental barrier coating. A thermal spray feedstock for producing a rare earth silicate-based hermetic layer.

A seal system, for an apparatus that includes a rotatable portion with airfoils coupled thereto and a stationary portion with an inner surface, includes an abradable portion including at least one abradable layer of an abradable material formed over the inner surface. The seal system also includes an abrading portion disposed over at least a portion of a substrate of the airfoil. The abrading portion includes at least one abrading layer formed on at least a portion of the substrate and a plurality of abrasive particles embedded within the abrading layer. The plurality of abrasive particles includes at least one of substantially all of one of tantalum carbide (TaC), aluminum oxide (AlO), and ziconia (ZrO), cubic boron nitride (cBN) and AlOin predetermined ratios, cBN, AlOand ZrOin predetermined ratios, AlOand ZrOfused together in predetermined ratios, and TaC and AlOin predetermined ratios.

An apparatus for enhancing the coalescence of a dispersed phase from a continuous phase in an emulsion is presented. The apparatus includes at least one inlet for receiving the emulsion, at least one outlet for discharging the emulsion after coalescing the dispersed phase, and at least one article disposed between the inlet and the outlet. The article includes a plurality of regions disposed on a surface in a predefined pattern, wherein a portion of the plurality of regions is substantially wetting with respect to the dispersed phase, and a portion of the plurality of regions is substantially non-wetting with respect to the dispersed phase, and wherein the pattern includes a plurality of inter-connected regions that are substantially non-wetting with respect to the dispersed phase. A related article is also presented.
