摘要：
A number of porous substrates (10) are arranged alternately in contact with layers (12) forming metal-based composition sources. Each layer includes a major phase consisting of the metal-based composition and a minor phase capable of forming a structure for retaining and draining the molten metal-based composition. The load is heated to a temperature higher than the melting point of the metal-based composition so that said molten metal-based composition can migrate from each source into the substrate through the adjacent surface of the or each substrate adjacent to the source. The method is particularly suitable for delivering a silicon composition into a thermo-structural composite material, in particular a carbon-carbon composite material, for silicidising purposes.
