Influence of the wetting angle on capillary forces in pressure infiltration

Andreas Mortensen, Ludger Weber, Alain Léger

This work probes the influence of wetting on pressure infiltration. Pressure/saturation curves for the infiltration of packed F1000 angular alumina particle preforms by liquid Cu-Al and Sn-Al alloys are measured using an instrumented high-temperature press ...

Infiltration of tin bronze into alumina particle beds: influence of alloy chemistry on drainage curves

Andreas Mortensen, Ludger Weber, Alain Léger

The wetting of angular alumina particle preforms by Cu-Sn alloys is investigated by means of pressure infiltration experiments conducted at 1150 A degrees C, using a system enabling dynamic and precise measurements of the metal volume injected into the pre ...

Capillarity in pressure infiltration: improvements in characterization of high-temperature systems

Willy Dufour, Andreas Mortensen, Ludger Weber, Raphaël Charvet, Alain Léger, Claudio Bacciarini, Noelia Rojo Calderon

In the pressure infiltration of metal matrix composites, molten metal is injected under external pressure into a porous preform of the reinforcing material. Equilibrium capillary parameters characterizing wetting for this process are summarized in plots of ...
