Abstract
A workpiece support member can rotate about an axis relative to a source, and the source can emit a plume of coating material that flows toward the workpiece support member approximately parallel to the axis. A plume-influencing shield can rotate with the workpiece support member, and has a plurality of openings extending therethrough approximately parallel to the general direction of flow of the plume. According to a different aspect, a method involves: rotating a workpiece support member about an axis relative to a source; emitting from the source a plume of coating material that flows toward the workpiece support member approximately parallel to the axis; and influencing the plume with structure that includes a shield rotating with the workpiece support member, the shield having a plurality of openings extending therethrough approximately parallel to the general direction of flow of the plume.
