Internal Stresses in Diffusion Bonded Joints

Abstract

using diffusion welding and bonding processes. Several types of interlayers and amorphous filler metals were tested. Vacuum bonded joints using amorphous filler metals have shear strength up to 260 MPa – 350 MPa. The applicability of mechanical metallization process with rotating titanium brushes to get a thin film on the cermets was tested. Electrochemically and mechanically deposited films of Ag, Ni and Ti were used to improve the wettability and strength of the joints. Internal stresses in the diffusion bonded joints depend on the type of a cermet and the interlayer used in the joining process.
