Multifunctional Ceramic Nanocomposites with Self-Diagnostic Ability of Catastrophic Damage
Read full article onlineFull Article
Ceramic nanocomposites are widely used as engineering materials owing to their excellent mechanical properties. In the last decade ceramic nanocomposites found new uses as a different kind of sensor. In this entry, examples of the preparation of electroconductive ceramic nanocomposites are shown together with their utilization as self-monitoring sensors for crack initiation and propagation. Four different methods for synthesis of nanocomposite ceramics are presented, and their effects on the structure of nanocomposites are compared. The self-diagnostic ability of graded and layered ceramic nanocomposites was not accompanied by any sizable deterioration of mechanical properties.
