Abstract
Wetting of liquid metal alloys to solid substrates is governed by Young's equation, which relates the degree of wetting to the combined influence of solid-liquid, solid-vapor, and liquid-vapor surface tensions. It is important that a liquid metal alloy source exhibit good wetting with a near-zero contact angle. The wettability of several B-containing alloy systems is considered, with emphasis on the role of surface segregation on contact angle.
