Abstract
A method for manufacturing a leak tight porous component includes the steps of forming a porous component; applying a first application of a surface sealant layer to the component; providing pressurized gas into a wall of the component via a known leak in the surface sealant; applying liquid to the component while pressurized gas is flowing into the wall of the component via the known leak. The method further includes the steps of inspecting the component for the formation of bubbles; identifying a new leak area in the component; removing at least a substantial amount of liquid from the component; and applying a second application of surface sealant to the new leak area.
