Stainless Steel Metallization and Brazing
I need a hermetic ceramic-to-metal seal or feedthrough. Who metallises and brazes it?
What it is
Depositing thin metal layers, typically tungsten or copper, onto a ceramic surface so that filler metal will wet it, then brazing the ceramic to metal hardware. This is how a ceramic becomes part of a hermetic assembly, which it otherwise cannot.
