Floating catalyst chemical vapor infiltration of nanofilamentous carbon reinforced carbon/carbon composites–Tribological behavior and wear mechanism

Nanofilamentous carbon (NFC) reinforced carbon/carbon composites were produced by floating catalyst chemical vapor infiltration. The study on the tribological properties showed that, the average friction coefficient and wear rate decreased firstly before an increase with the rising catalyst content from 0 to 1.2 wt% and treatment temperature from 2100 to 2500 °C. The composites exhibited low wear rate and stable friction coefficient with the...
