Spark plasma sintering of electro conductive nanocomposite Al₂O₃-SiCw-TiC

Abstract

The method of production nanostructured ceramic Al2O3-SiCw-TiC with high operational properties by spark plasma sintering is developed in this work. The obtained nanoceramic material was compared to Al2O3-SiCw. The homogenous compound of initial nanostructured powders of different phases and sizes was made by the methods of colloid blending and spraying. The microstructure, hardness, fracture strength, phase’s analysis, electro conductive properties of the samples were researched. The electro conductivity of sintered nanocomposite Al2O3-SiCw-TiC enables to process it by electrical discharge machining.
