Abstract: A coating process for applying a bifurcated coating to an article is disclosed including applying an aluminizing slurry to a first portion of the article, applying a chromizing slurry to a second portion of the article, and simultaneously heat treating the article, the aluminizing slurry, and the chromizing slurry. Heat treating the aluminizing slurry forms an aluminide coating on the first portion of the article and an aluminide diffusion zone between the article and the aluminide coating. Heat treating the chromizing slurry forms a chromide coating on the second portion of the article and a chromide diffusion zone between the article and the chromide coating. The first portion and the second portion are both maintained in an unmasked state while applying the aluminizing slurry and the chromizing slurry and during the heat treating.

Abstract: Methods for preparing a hybrid article include disposing an additive structure comprising a plurality of layers on a build surface of a part, the build surface being defined based on x, and y coordinates, and the additive structure being defined by a three dimensional model defined by a series of planes based on x, y and z coordinates that define a plurality of layers, one layer comprising an interface surface having a contour being defined by x, and y coordinates. When the build surface and the interface surface are both oriented in space according to corresponding x, y and z coordinates, a cladding system is directed to deposit each of the sequential layers of the additive structure according to toolpaths that correspond with each of the plurality of layers of the three dimensional model.

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.
