Abstract

An apparatus includes a workpiece support, a source for emitting a plume of coating material that flows toward the workpiece support, and plume influencing structure between the source and the workpiece support. The plume influencing structure includes a shield with plural openings extending therethrough approximately parallel to a general direction of flow of the plume away from the source. According to a different aspect, a method includes emitting from a source a plume of coating material that flows toward a workpiece support, and adjusting the flow of the plume with a shield between the source and the workpiece support, the shield having plural openings extending therethrough approximately parallel to a general direction of flow of the plume.
