Microhardness of Silicon Nitride Ceramic and Its Composites

Micro hardness research studies on various non oxide ceramics will be carried out. These ceramics include silicon nitride and the composites of silicon nitride. Micro hardness measurement of these ceramics i.e. vicker will be carried out using diamond indenters. Various influences of load and time of indentation on hardness values of these ceramics will be carried out in detail. Fracture toughness of these ceramics was also studied using vicker indentation. The vicker hardness of these ceramics decreases with increasing load, similar influence was observed by increasing time of indentation. Showket Hussain Dar | Er.
