【 摘 要 】
Multi-layered ceramic composites with alternation of grain sizes in layers were produced by adding thin interlayers ofgraphene-augmented alumina nanofibres (GAIN) between layers of monolithic α-Al2O3. The composite was mounted layer bylayer directly in the graphite mould, using a vacuum filter system to precipitate alumina nanopowder and GAIN layers from thecorresponding suspensions. The 30-mm diameter samples were consolidated by the spark plasma sintering technology at 1450 °Cin nitrogen atmosphere at 50 MPa pressure. The effect of interlayers on the microstructure of alumina and on the thermal andelectrical conductivity of the compact is studied.
