Abstract
In this study the wettability and interfacial behaviour of the TiC–FeNiCrBSiC and TiB2–FeNiCrBSiC systems were investigated. The wetting experiments were performed by the sessile drop method at 1150°C under a vacuum. The contact angles of TiC and TiB2 wetting by melted Fe-based self-fluxing alloy were 51° and 36°, respectively. Thermodynamic calculations were carried out to understand the metal–ceramic interaction mechanism in the TiC–FeNiCrBSiC and TiB2–FeNiCrBSiC systems. The structure of the interface region in the TiB2–FeNiCrBSiC system was characterized by the optical microscopy and SEM-EDS analysis. The formation of Fe, Ni, Cr and Mo complex borides was revealed within the interface region of the TiB2–FeNiCrBSiC system.
