Diffusion Bonding Zirconium Alloys to Steels

Abstract

Diffusion bonding has been developed to join zirconium alloys to carbon steel, providing a strong, tough, compact and leak-tight joint. The quality of the joint is verified by means of a variety of mechanical, corrosion and irradiation tests. The method of manufacture is described. Long-term service tests are presently being mounted. Potential and actual applications to the CANDU-PHW* system are discussed.
