Abstract
A joining method includes placing a brazing element between an interface area of a first ceramic piece and an interface area of a second ceramic piece to create a joining pre-assembly and placing the components of said joining pre-assembly into a process chamber. Oxygen is removed from said process chamber and at least said brazing element of said joining pre-assembly is heated, thereby hermetically joining said first ceramic piece to said second ceramic piece. Said brazing element consists of Cobalt and Carbon.
Claims18
A joining method, said joining method comprising the steps of:
- placing a brazing element between an interface area of a first ceramic piece and an interface area of a second ceramic piece to create a joining pre-assembly, wherein said brazing element consists of Cobalt and Carbon;
- placing the components of said joining pre-assembly into a process chamber;
- removing oxygen from said process chamber;
- and
- heating at least said brazing element of said joining pre-assembly, thereby hermetically joining said first ceramic piece to said second ceramic piece.
