Abstract: A process for forming a thermal barrier coating system on a substrate is disclosed including preparing a slurry including a donor powder, an activator powder, and a binder. The donor powder includes a metallic aluminum alloy having a melting temperature higher than aluminum, and the binder includes at least one organic polymer gel. The process further includes applying the slurry to the substrate, heating the slurry to form an aluminide bond coating including an additive aluminide layer and an aluminide interdiffusion zone disposed between the substrate and the additive aluminide layer, and applying a thermal barrier coating to the aluminide bond coating. The thermal barrier coating may be a dense vertically-cracked thermal barrier coating, and the substrate may be a gas turbine component. Thermal barrier coating systems formed by the process are also disclosed.

Abstract: Delayed coking drum quench overflow systems and methods, which relate to removing hydrocarbon particulates from an overflow stream in a delayed coking drum quench operation. In one embodiment, an improved overflow system incorporates one or more filters to remove hydrocarbon particulates from the system before passing through a conventional closed blowdown system.

Abstract: Certain embodiments of the invention may include systems methods, and apparatus for sealing a bucket dovetail in a turbine. According to an example embodiment of the invention, a method is provided for sealing a gap between a bucket dovetail and a rotor wheel slot. The method can include modifying a bucket tab associated with the bucket dovetail to accept a seal tab, wherein the seal tab is configured to expand as a function of temperature; maintaining the seal tab in contact with the modified bucket tab; sealing a gap between the bucket dovetail and the rotor wheel slot with the seal tab; and modifying at least a portion of the seal tab as a function of temperature for further sealing gap between the bucket dovetail and the rotor wheel slot.

Abstract: A compliant seal assembly for sealing a gap between a dovetail tab of a bucket and a slot of a rotor. The compliant sealing assembly may include a sealing groove positioned about the slot and a compliant seal positioned about the sealing groove. The compliant seal is forced into the gap and about the dovetail tab when the bucket rotates.

Abstract: A sealing slot system for a turbine dovetail. The sealing slot system may include a dovetail tab with a first leg and a second leg, an insert positioned between the first leg and the second leg so as to define a sealing slot, and a pin extending through the dovetail tab and the slot insert.

Abstract: A dovetail seal assembly for sealing a gap between a bucket dovetail and a rotor. The dovetail seal assembly may include a sealing slot positioned about the dovetail, a high-pressure supply hole in communication with the sealing slot, and a deformable seal positioned about the sealing slot and into the gap.

Abstract: A spring seal system for a turbine dovetail tab. The spring seal system may include a sealing slot positioned about the tab and a spring seal positioned within the sealing slot. The spring seal may include a substantial “U” shape.
