    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.

    Abstract: A method includes generating a plasma plume with a plasma gun, delivering a plurality of coating materials to the plasma plume with a powder feeder assembly to vaporize the coating materials. The delivery includes delivering a first (bond coat) material from a first powder feeder to the plasma gun, ceasing delivery of the first material, increasing a rate of delivery of a second (rare earth stabilized zirconia) material from a second powder feeder to the plasma plume, increasing a rate of delivery of a third material (a rare earth stabilized zirconia material different from the second material) from a third powder feeder to the plasma plume, decreasing a rate of delivery of the second material, and decreasing a rate of delivery of the third material, and depositing the plurality of coating materials on a work piece to produce a layered coating with blended transitions between coating layers.

    Abstract translation: 一种方法包括用等离子体枪产生等离子体羽流,用粉末供料器组件将多种涂料输送到等离子体羽流以蒸发涂层材料。 交付包括将第一(粘合涂层)材料从第一粉末进料器输送到等离子体枪,停止第一材料的输送,增加第二(稀土稳定的氧化锆)材料从第二粉末进料器输送到 等离子体羽流,将第三材料(稀土稳定的氧化锆材料与第二材料不同)的输送速率从第三粉末进料器提高到等离子体羽流,降低第二材料的输送速率,并降低 递送第三材料,以及将多个涂层材料沉积在工件上以产生具有在涂层之间的混合过渡的分层涂层。
