| Abstract: | Sapphire and Nb alloy have been successfully brazed by use of tungsten-metallization technique. The experimental results show that the content of Y2O3 in the metal layer on the sapphire affects the vacuum leakage and the bonding strength of sapphire-Nb alloy brazing parts. Furthermore, the sapphire-Nb alloy brazing structures act the key role for the resistance to repeated heat shock. |
