摘要
Metal matrix composites are made by infiltrating packed loose fly ash with molten metal or metal alloy under low pressure. In some embodiments the infiltration is driven by pressurized gas. Coating the fly ash prior to infiltration can lower the threshold of pressure required for satisfactory infiltration by the molten metal. In some embodiments nickel coated cenosphere fly ash is employed. Resulting metal-fly ash composites have high volume fractions of fly ash, and the fly ash is uniformely distributed in the metal matrix. The densities of the composites are relatively low, particularly in composites made using cenosphere fly ash.
