“…Many commercially available brazing alloys meet the main mechanical requirement of metal/ceramic joints, in which the more frequently used braze includes a Cu-Zn based alloy. Addition of small quantities of Ti increases the ceramic wettability and reactivity by diffusion of Ti across the interface (Zhang & He, 2010;Zou et al, 2009 ). The Figure 8 shows a cross-section interface of diffusion bonding Si 3 N 4 /Cu/Ti combinations joined at temperature of 980°C.…”
