Diffusionless bonding of aluminum to Zircaloy-2
Aluminum can be bonded to zirconium without difficulty even when a thin layer of oxide is present on the surface of the zirconium. No detectable diffusion takes place during the bonding process. The bond layer can be stretched as much as 8% without affecting the bond. The bond can be heated for 1000 hours at 260 deg C (500 deg F), and can be water quenched from 260 deg C (500 deg F) without any noticeable change in the bond strength. An extrusion technique has been devised for making transition sections of aluminum bonded to zirconium which can then be used to join these metals by conventional welding. Welding can be done close to the bond zone without seriously affecting the integrity of the bond. This method of bonding aluminum to Zircaloy-2 is covered by Canadian patent 702,438 January 26, 1965.
