The reaction layer thickness at the Al2O3/AgCuTi interface has been measure
d with different bonding times at a fixed bonding temperature. The effect t
hat the change in reaction layer thickness had on the shear strength of a A
l2O3/AgCuTi/Ti-6Al-4V brazed joint was analysed using SEM. The relationship
between reaction layer thickness and joint strength has been discussed wit
h the aim of providing a theory for guiding industrial manufacture and incr
easing the joint strength.
