Abstract

Abstract The wettability of pure Ag and Ag alloys (with Ni and Cu) on WC was investigated as a function of temperature by means of sessile drop experiments. Ni was found to preferentially segregate at the Ag/WC interface resulting in a decreased contact angle as compared to Cu. The influence of the Ni content and WC particle size on the solidification behavior of Ag in infiltrated Ag-WC-Ni (40 wt% WC and 0.07/5 wt% Ni) composites was assessed, revealing the pushing of WC particles by the solidification front, especially in the materials with a finer WC particle size. Addition of Ni decreased the grain size of the Ag phase by promoting heterogeneous nucleation. Complete coherency between the Ag and Ni phases was confirmed by electron backscattered diffraction analysis.
