Abstract: A method treats a brush seal at a tip end of the brush seal. The method includes contacting the tip end of the brush seal to an oxidation-resistant, wear-resistant coating composition and heat-treating a distal portion of the bristles to form an oxidation-resistant, wear-resistant coating on the distal portion from the oxidation-resistant, wear-resistant coating composition. A brush seal includes a brush support and bristles extending from the brush support with a distal portion coated by an aluminide diffusion coating. A brush seal assembly includes a non-rotary component and a rotary component. The non-rotary component includes a brush seal including a bristle pack. The bristle pack includes bristles extending from a brush support with a distal portion coated by an aluminide diffusion coating. The rotary component has a sealing surface contacting the distal portion of the brush seal to form a turbine seal between the rotary component and the non-rotary component.

Abstract: A system and method for repairing a metal substrate includes an electrospark device and an electrode removably supported in the electrode holder. The electrospark device applies a coating of a material when placed into contact with the metal substrate. A cooling device to lowers the temperature of shielding gas flow below an ambient temperature. A conduit is arranged to direct a flow of the shielding gas to the interface of the electrode and the substrate to cool the area of the substrate receiving the coating.

Abstract: A slurry and a coating method are provided. The slurry includes, by weight, between 10% and 40% metal powder, between 10% and 15% activator, between 10% and 20% adhesive, between 10% and 20% thickener, up to 30% ceramic, and up to 25% binder. The coating method includes providing a slurry including, by weight, between 10% and 40% metal powder, between 10% and 15% activator, between 10% and 20% adhesive, between 10% and 20% thickener, up to 30% ceramic, and up to 25% organic polymer binder, providing a substrate, applying the slurry over a surface of the substrate to form a slurry coating, drying the slurry coating over the substrate, baking the substrate and the slurry coating, and curing the slurry coating over the substrate. The curing the slurry coating over the substrate transfers metal elements of the metal powder in the slurry to the substrate to form a coating on the substrate.
