Abstract (en)
[origin: EP1013890A2] The contact seal consists entirely of a foamed metallic corrosion-resistant high-temperature alloy, fixed to the wall sector by high temperature soldering. Since there is no open-pore structure, the solder is not taken into the seal structure by capillary attraction, so the foam is easy to solder. The unfoamed raw material may first be connected to the wall sector, and then foamed.
