Microstructural and process characterization on the electrical conductivity and electrical discharge machinability of Al2O3-based ceramic composites

Due to the inherent microstructural properties, ceramics have been viewed as insulating, dielectric or low conductive materials. Hence, the low electrical conductivity of ceramics makes the machining process using electrical discharge machining (EDM) very difficult as it is economical than machining...
