Morphology and composition of inclusions in aluminium are identified using before and after filtration using optical microscope, SEM, XRD and EPMA. Qualitative analysis of results form various filtration experiments indicates that CFF filtration is an effective process to remove inclusions from molten aluminium. Interaction between inclusions and filter materials is investigated, which includes the effects of surface energy change before and after attachment, inclusion size, and fluid flow. Mechanisms of inclusion removal through filtration are then proposed. Both uncoated and slurry coated Al2O3 CFFs were found to have very good filtration efficiencies. However, qualitative analysis showed that the uncoated filter has more excellent filtration capabilities than the slurry coated filters.enAluminumFiltrationInclusionsArticle
