Abstract
A method for forming non-separating diffusers in a part includes fabricating at least one metering hole in a part, and fabricating at least one diffuser hole with an electrode comb in the part such that the diffuser hole intersects the metering hole at a transition region. The electrode comb includes a tooth including a nose comprised of a plurality of diffuser surfaces intersecting at a point on a tooth centerline. Each diffuser surface has a diffuser angle, and at least one of the diffuser surfaces is truncated by an offset from the tooth centerline.
