Summary

An experimental technique for evaluation of wettability of ceramic particulate with liquid metal was developed. Wettability tests were conducted by pressure infiltration through uniformly packed powder specimens. The threshold pressures for infiltration can either be used as quantitative measure of wettability or be converted to wetting angles by using the capillary force equation. With this technique, wettability was measured for SiC and B4C particulates with liquid aluminum alloys. The effects of temperature, time, and alloying element on wettability were investigated. Theoretical calculations of solid-liquid interfacial energy were also reviewed briefly.
