Cemented Carbide Composite

Cemented carbide - Wikipedia

Cemented carbides are metal matrix composites where carbide particles act as the aggregate and a metallic binder serves as the matrix (like gravel aggregate in a matrix of cement makes concrete). Its structure is thus conceptually similar to that of a grinding wheel, except that the abrasive particles are much smaller; macroscopically, the material of a carbide cutter looks homogeneous. The process of combining the carbide particles with the binder is referred to as sintering or hot isostatic p…
