摘要

Process for pressure infiltrating porous components comprises covering the component with a first infiltration liquid, liberating the component from the liquid and solidifying remaining part, dipping the sealed porous component into a second infiltration liquid, and impinging the second region not covered with the gas-tight layer with a low pressure, and removing the porous component from the liquid after infiltration is complete. Process for pressure infiltrating porous components comprises covering the component with a first infiltration liquid so that at least two regions of the component surface do not contact the liquid, liberating the component from the liquid and solidifying remaining part so that a gas-tight layer is formed on and/or in the edge regions of the components, dipping the sealed porous component into a second infiltration liquid so that the first of the regions not covered with the gas-tight layer comes into contact with the liquid, and impinging the second region not covered with the gas-tight layer with a low pressure, and removing the porous component from the liquid after infiltration is complete.
