Abstract
Boron carbide is one of the most promising structural ceramics; therefore its joining to other ceramics and metals is of technological importance. In this study, interface interactions and joints strength were studied in various cases of B4C/Cu based fillers (Cu-9at%B, Cu-4.5at%Ti and Ticusil®). The fillers partially wet B4C (q < 500), but the interface composition and morphology are different. In the B4C/Cu-9at.%B system no new phases are detected at the interface, while the formation of TiB2 takes place in the case B4C/Cu-4.5at%Ti, and a double layer containing TiB2 and TiC is formed at the B4C/Ticusil® interface.
The maximal shear stress for B4C/B4C joints breakage was obtained for the Cu-9at.%B brazing alloy which displays partial wetting without the formation of brittle phases at the ceramic/metal interface.
This study shows that improved wetting is essential but not sufficient in order to obtain strong bonding between B4C and the fillers examined.- Full Text:
