摘要
The performance of diffusion bonding is critically dependent on the surface finish and the bonding pressure holding the mating surfaces together for an appropriate time. Effects of surface finish and pressure on the bonding performance of Ti-25Al-10Nb-3V-1Mo super alpha two titanium aluminides were investigated at the temperature of 1000 degrees C for 1 h holding time. Results showed that successful diffusion bonding was achieved using 800 Grit/15 MPa and 180 Grit/20 MPa surface finish and pressure combinations. It was also shown that the bonding pressure and surface finish combinations used in this study affected the microstructure and the physical appearance of bond line in all specimens.
