Abstract: Various embodiments include a gas turbine seal and methods of forming such seal. The method of forming the seal includes forming a freestanding ceramic seal for sealing in a gas turbine by applying a ceramic material on a substrate to form a ceramic layer, removing the substrate from the ceramic layer and finishing the ceramic layer to define the freestanding ceramic seal. The method includes depositing particles of the ceramic material in one of a molten or vapor state on a surface of the substrate and quenching the ceramic material to form the ceramic layer. The ceramic material comprises yttria-stabilized zirconia having a t′ tetragonal structure. A gas turbine including the freestanding ceramic seal is additionally disclosed.

Abstract: A coated seal slot system for turbomachinery includes a first turbine component comprising a first groove having at least one first coating attached to at least a portion of the first groove of the first turbine component, a second turbine component comprising a second groove having at least one second coating attached to at least a portion of the second groove of the second turbine component. The first and the second turbine components are disposable adjacent to each other with the first groove having the first coating and the second groove having the second coating together forming a coated seal slot extending across a gap between the first turbine component and the second turbine component. A seal is disposable in the coated seal slot and extendable across the gap between the first and the second turbine components and engageable with the first coating and the second coating to inhibit leakage of gas through the gap.

Abstract: A mixing device having a mixing container and has a single-shaft agitator that extends into the mixing container. At the end of the drive shaft, a rotor body is arranged slightly above the bottom of the mixing container. The rotor body comprises a plurality of mixing blades, wherein the blades are, in one example, star-shaped and fixed in position to each other. A first end of the drive shaft is coupled to a motor and a second end of the drive shaft is configured to extend into the mixing vessel, wherein the blades are attached onto the second end of the drive shaft. The blades in one example include at least two coincidental knife-edged blades such that at least one of the knife-edged blades is facing upward. The mixing device in one example is used to mix calcium aluminate-containing slurries.
