Vapor aluminide coating gas manifold

摘要

A manifold for use in a process for coating different sized passages in a workpiece is provided. The manifold has an internal chamber, an inlet for receiving a flow of a coating gas, and a flow diverter within the internal chamber for separating the flow of coating gas into a first flow sufficient to coat a full length of surfaces of a first internal passage set having a first cross section dimension and a second flow sufficient to coat a full length of surfaces of a second internal passage set having a second cross section dimension smaller than the first cross section dimension.
