Abstract
The process of vacuum brazing including traditional furnace brazing and infrared brazing Ti-6Al-4V alloy using the Ti-15Cu-15Ni filler metal was investigated. The wetting angle measurement, microstructural evolution, and shear strength of the brazed joint are extensively assessed in the experiment. The substrate was polished by SiC papers up to 1200 grits, and subsequently cleaned using an ultrasonic bath with acetone as the solvent prior to brazing. Ti-6Al-4V can be readily brazed using the Ti-15Cu-15Ni as the brazing filler metal. Minimum erosion of the base metal is obtained from the infrared brazed joint at 970°C for 180 s due to its rapid thermal history.
