Some observations in grinding SiC and silicon carbide ...

May 10, 2019· 10%· The extension of cracks is the main removal method during grinding process of SiC. While matrix craze, fiber fracture, and interfacial debonding are the main remove methods of Cf/SiC composites. While grinding 2.5 D Cf/SiC material, fiber pullout, outcrop, fractures, wear, interfacial debonding, and matrix cracks were the major failure forms.

The optimisation of the grinding of silicon carbide with ...

Jul 22, 2003· The grinding of silicon carbide is difficult because of its low fracture toughness, making it very sensitive to cracking. The efficient grinding of high performance ceramics involves the selection of operating parameters to maximise the MRR while maintaining the required surface finish and limiting surface damage.
