    Abstract: An apparatus for applying segmented ceramic coatings includes means for supporting and moving one or more substrates; one or more heat sources disposed proximate to one or more substrates, wherein at least one of the heat sources is positioned to apply a heat stream to pre-heat a thermal gradient zone on a surface of a substrate; a material deposition device disposed proximate to one or more heat sources, wherein the material deposition device is positioned to deposit a material on a deposition area located behind the thermal gradient zone on the surface; and means for monitoring a surface temperature of one or more substrates.

    Abstract: THERMAL BARRIER COATING A bond coat is applied to a substrate of a gas turbine engine component the component. A barrier coat is applied atop the bond coat. The applying of the bond coat includes: applying a first layer having an as-applied first roughness; and applying a second layer atop the first layer, the second layer having an as- applied second roughness, greater than the first roughness. In the resulting coating system, the first and second layers may have different properties (e.g., greater porosity, pore size, and/or splat size for the second layer).

    Abstract: A powder port blow-off system for a plasma spray process includes a faceplate that includes a bore therein that is co-radially aligned with a nozzle of a plasma spray gun, which emits a plasma plume. A plurality of powder feed ports are arranged circumferentially around the nozzle for injecting a flow of powder particles toward the plasma plume. A plurality of powder port blow-offs are arranged circumferentially around the nozzle in order to direct blow-off gas across the powder feed ports. The powder port blow-offs are directed across the plasma plume to create a vortex for carrying away powder particles unconsumed by the plasma plume.

    Abstract: A turbine article includes a substrate with a geometric surface feature having a plurality of recesses recessed into the substrate. A ceramic topcoat is disposed over the geometric surface feature. The topcoat includes portions that are separated by faults extending through the topcoat from the geometric surface feature so the topcoat is segmented. A ceramic interlayer is disposed between the topcoat and the geometric surface feature.
