CERMETS are a class of very hard and tough materials which combine the hardness of ceramics with the toughness of very wear resistant metals. Tungsten Carbide grinding drill bits is a primary example of a CERMET. Specimen preparation of these materials requires diamond grinding and polishing abrasives.Preparation Challenge:
Proper specimen preparation requires that grinding damage be minimized as early as possible followed by polishing with CMP (chemical mechanical polishing) polishing techniques.
