    Abstract: A method includes applying a material coating to a surface of a machine component, wherein the material coating is formed from a combination of a hardfacing material, aluminum-containing particles, and a braze material. The method also includes thermally treating the material coating at a temperature to generate an oxide layer comprising aluminum from the aluminum-containing particles, wherein the oxide layer is configured to reduce oxidation of the hardfacing material, and the braze material is configured to facilitate binding between the material coating and the surface of the machine component.

    Abstract: A method of depositing a coating on a component of a turbine engine. The method includes forming a turbine component including at least one cooling flow passage in fluid communication with an aperture on a surface of the turbine component. A protective shield is formed on an inner surface of the at least one cooling flow passage and extending to an exterior of the turbine component via the aperture. During a coating process, the protective shield is configured to block the coating from being deposited in the at least one cooling flow passage via the aperture. Subsequent to coating, at least a portion of the protective shield is removed to provide for passage of a cooling fluid flow in the at least one cooling flow passage. The cooling fluid flow exits the turbine component through the aperture. A turbine component employing user of the protective shield is also disclosed.

    Abstract: A method of making an article of manufacture is provided and includes the steps of spraying a first coating onto a substrate, and depositing a second coating on the first coating by 3-D printing a material disposed in a pattern. The pattern includes ridges disposed at a base surface of a turbine part. Each ridge defined by first and second sidewalls, each sidewall having a first and second end. The ends extend from the base surface, the sidewalls slope toward each other until meeting at second ends of respective first and second sidewalls defining a centerline and a top portion of the ridge. The sidewalls are inclined with substantially equal but opposite slopes with respect to the base surface. The ridges correspond to a back portion of a turbine bucket and are oriented at a first angle with respect to an axis of rotation of the bucket.

    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.
