Verfahren zur Herstellung einer defektfreien Oberfläche auf einem porösen keramischen Substrat.

摘要

An object of the present invention is to provide a process for hermetically sealing defects (12) in a porous ceramic substrate (10) comprising the steps of evaporating or sputtering a malleable metal layer (14) onto the defective porous ceramic surface, swaging or smearing the malleable metal layer over the defects and depositing a second metal film (16) over the swagged first film to provide a smooth defect free surface.
