The wetting and spreading of molten aluminum on TiB2 substrates between the aluminum melting point and 1033 K (760 °C) was investigated in the presence of different types of fluxes. The wetting and spreading behavior is observed to depend on the flu

Examples of the impact of capillary phenomena on materials processing are drawn from the aluminum industry spanning aluminum smelting to recycling. The profound interaction of the oxides that form on molten aluminum is felt in many of the processes c

Titanium diboride is widely accepted to be completely wet by liquid aluminum, yet few published wetting studies demonstrate this behavior, and reported contact angles vary widely. Sessile drop substrates from four different sources were selected and

The rate of movement of liquid drops toward their equilibrium position on smooth, horizontal solid surfaces (spreading kinetics) is considered in this study. A model for nonreactive liquid spreading which was developed for low-temperature liquids is

Furnace brazing is commonly used in the electronic industry to attach I/O pins, lid-seal rings, and heat spreaders to cofired multilayer ceramic packages. Despite the widespread industry usage of electrolytic and electroless Ni coatings to render bas

Dynamic hot-stage microscopy and sessile drop experiments have identified three stages in the spreading of Ag–28 wt. % Cu liquid on the surface of high-purity Ni foil: (I) nonreactive flow, (II) secondary spreading, and (III) breakout flow. The fir

The wetting of tungsten by a Cr 2 O 3 colored, CaO-MgO-Al 2 O 3 -SiO 2 glass was found to be independent of temperature between 1300 o and 1500 o C, but strongly dependent on furnace atmosphere. Similar results using two gas buffer systems (CO/CO 2 a
