摘要：

In order to develop ED-machinable ceramics with high strength, toughness and wear resistance, ZTA was chosen as matrix material. A dispersion of 24 vol% electrically conductive phase (TiC, TiN, TiCN, TiB2 and WC) was added. These composites were hot pressed for 1h at 60 MPa and temperatures ranging from 1475 degrees C to 1550 degrees C. Mechanical and electrical properties were investigated. The influence of the electrically conductive phase on the surface quality after EDM was analyzed. The mechanical properties and machining quality were found to depend significantly on the type of conductive phase added. Machining of a complex shaped ZTA-TiC component was demonstrated.
