Abstract :
A functionally gradient material (FGM) of Al2O3–Ti3SiC2 was fabricated by spark plasma sintering (SPS) in vacuum. Its microstructure and properties were investigated. From examination of the dependence of the electrical conductivity on composition of the binary system Al2O3–Ti3SiC2, we determined the percolation threshold at which an interconnected network of electrically conductive phase arises. The hardness distribution across the entire composite was evaluated by Knoop indentation. The hardness was reduced with increasing content of Ti3SiC2.
