ABSTRACT
Diffusion bonding is a solid phase welding process in which bonding occurs through coalescence of the surfaces in contact. The principal operating parameters of diffusion bonding are the temperature, pressure and the bonding time. In addition to diffusion, other mechanisms such as microscopic creep or recrystallization also contribute to the formation and development of the bond. This article examines the influence of the surface oxide and welding atmosphere on mechanical characteristics of the bonded joint.
