Abstract
The basic mechanism of adherence in high‐alumina ceramic‐to‐metal sealing has been studied. A sealing mechanism has been established which involves the migration of the glassy phase of the high‐alumina ceramic into the interstices of the molybdenum‐based coating. The study was conducted on 94 and 99% aluminas, using molybdenum‐manganese, molybdenum‐titanium, and pure molybdenum metallizing compositions. The possibility of the formation of chemical compounds by either the molybdenum or the added metals has also been studied. A means of isolating and identifying any reacted or migrated phases has been developed.Keywords
