Notes
  • A discrete coating of aluminum particles on the surface of Al2O3 particles was prepared by the semi-solid mechanical stirring method. Al2O3 particles with an average diameter of 80 μm, preheated to about 300°C, were added to semi-solid pure aluminum to prepare a slurry by the mechanical stirring method. The volume fraction of Al2O3 particles in the slurry was about 20%. As the ceramic particles were uniformly dispersed in the semi-solid aluminum, the temperature of the slurry decreased quickly, but the slurry continued to be stirred until all the slurry was converted into composite powder. The composite powder was then cooled down to room temperature in a steel block cooler in an argon atmosphere. The surface morphology and transverse sections of the composite powder were examined using a scanning electron microscope (SEM), electron probe X-ray microanalyser (EPMA), optical microscope and augur electron spectroscopy (AES). The results indicate that the composite powder was a mixture of Al/​Al2O3composite particles and pure aluminum powder in quasi-spherical shapes. A single layer of nano-, submicron- and micron-sized aluminum particles were coated on the surfaces of the Al2O3 particles. The slurry could be converted into the composite powder resulting from faster solidification of liquid aluminum and mechanical stirring.
