Article Preview

Al/Al2O3 cermet composites were fabricated by hot-pressing at the temperature range of 1350~1450oC from commercial γ - Al2O3 reinforced by Al/Al2O3 core-shell particles, which were synthesized via calcining the Al/AlOOH·nH2O core-shell particles prepared by wet-chemical based method. This newly designed aluminum coated with alumina composite structure can not only reduce or resist the oxidization of Al at elevated temperature but also make it possible to control inter-particle and particle-matrix interactions, and this predesigned structure is expected to improve the following sintering ability and therefore the properties of final products.
