  • Bonding metal to ceramic
    Patent number: 4645117
    Abstract: A method of bonding a metal body to a ceramic body, particularly a method of bonding a TWT slow-wave helix to boron nitride support rods, involves depositing on one of the bodies an active metal layer, typically of titanium, to be sandwiched between barrier layers protecting it from oxidation. The assembly is formed and then heated to a temperature sufficient to cause the active metal to migrate into the surface of the ceramic, whereupon the temperature is further raised to cause the protective barrier layers to form a braze uniting the metal body to the now-metallized ceramic body.
