摘要 |
A process for hermetically sealing defects in a porous ceramic substrate comprising the steps of evaporating or sputtering a malleable metal layer onto the defective porous ceramic surface, swaging or smearing the malleable metal layer over the defects and depositing a second metal film over the swaged first film to provide a smooth defect free surface.
