Abstract: A method and apparatus for uniting workpieces of silicon-infiltrated silicon carbide with large dimensions includes surrounding each of two silicon-infiltrated silicon carbide workpieces with at least one tightly closing shell in the vicinity of a junction between the workpieces, defining at least one intermediate space between the shell and the workpieces. A vacuum or an inert gas atmosphere is maintained in the intermediate space or spaces. Solder is placed at the junction and the junction is locally heated to soldering temperature for materially bonding the workpieces by soldering at the junction.

Abstract: A method for producing a metallic component provided with a ceramic lining in a mold includes applying a first ceramic layer to a mold. A sliding layer is applied to the first ceramic layer. A second ceramic layer divided by joints into individual zones is applied to the sliding layer. The second ceramic layer is coated with a metal forming a finished component.
