    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: 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.
