In the framework of joining processes of Ultra High Temperature Ceramics (UHTCs), sessile drop experiments were performed in the Ni-B/ZrB2 system in the range 1110°≤T≤1200°C. They show that, at temperatures between 1110 and 1150°C, isothermal solid-liquid transitions occur in a sequence; while in fact at T≥1200°C the drop melts without any...

Abstract An investigation of melting equilibria in the Ni-rich part of the Bsingle bondNisingle bondZr system was carried out by means of a combined experimental and computational approach, in order to improve the interpretation of wetting experiments of Bsingle bondNi alloys on ZrB2 substrates. Several samples along the Nisingle bondZrB2...

Metal-ceramic joints represent an important choice for biomedical devices, in orthopaedic field or as micro-stimulators. ZrO2-Ag-HEA joint is here proposed to replace the currently used Ti6Al4V by new Ti-based refractory HEAs. To evaluate the system reactivity, wettability of ZrO2 by different Ag-based alloys at 1000 degrees C and their...
