Abstract: A method for coating a substrate includes suspension plasma spraying of a size distribution of a ceramic powder of essentially uniform chemical composition to form a first ceramic layer. The size distribution has a trough spanning a transition size for powder behavior of gas-flow trajectories of smaller particles and ballistic trajectories of larger particles.

Abstract: A thermal barrier coating is applied to a turbine engine component having a substrate. The thermal barrier coating has a first layer which has a strain tolerant columnar microstructure at an interface with the substrate for spallation resistance and a second layer which is porous conduction and radiation thermally resistant at an outer surface of the thermal barrier coating.

Abstract: A ceramic coating process comprises introducing a suspension including a fine ceramic particulate suspended in a liquid carrier into a plasma torch. The fine ceramic particulate comprising a first material having high toughness and a second material having a beneficial reaction in combination with calcium-magnesium alumino-silicates. The method includes melting the fine ceramic particulate in the plasma torch; propelling the fine ceramic particulate toward a substrate; and forming a coating on the substrate. The coating comprises splats of the fine ceramic particulate.

Abstract: An embodiment of an apparatus includes a first crucible in communication with a deposition chamber, an energy source, and a workpiece fixture. The first crucible includes a plurality of walls defining an upper recess and a first lower recess, at least the upper recess open to an interior of the deposition chamber. The energy source is configured to selectively apply and direct energy within the deposition chamber, including toward the first crucible. The workpiece fixture includes tooling and a plurality of workpiece holders configured to retain at least one workpiece selectively within the deposition chamber. The tooling includes at least one wall separating at least a first of the plurality of workpiece holders from a second of the plurality of workpiece holders.

Abstract: An embodiment of a method includes retaining a first workpiece and a second workpiece selectively on a workpiece fixture disposed within a deposition chamber. The workpiece fixture includes tooling including a first workpiece holder, a second workpiece holder, and a first hollow wall. The first workpiece is separated from the second workpiece using the first hollow wall. Energy is selectively applied and directed within the deposition chamber, from an energy source toward a first crucible, the first crucible including a plurality of walls defining an upper recess contiguous with, and disposed directly above a first lower recess, at least the upper recess open to an interior of the deposition chamber. During the step of selectively applying and directing energy, a gas valve is controlled to maintain a partial vacuum in the deposition chamber of greater than 2 Pa to control a size and overlap of at least one coating zone formed around each of the at least one workpiece.
