摘要 |
The invention includes within its scope a method for producing a dual porosity body from a substrate having a plurality of passageways traversing the substrate and connecting a first surface with a generally opposing second surface by depositing a solid material onto the walls of at least a portion of the passageways adjoining only the first surface and stopping the deposition when the diameter of the passageways being coated have been reduced to a predetermined value.
