Friction and wear properties of C/C and ceramic particle dispersed C/C composites sliding against sialon ceramics were investigated in a zinc plating bath.
The results are summarized as follows:
(1) SiC particle dispersed C/C has the highest friction coefficient and the lowest wear resistance. BN particle dispersed C/C has lower friction coefficient but lower wear resistance than C/C composite. Y2O3 particle dispersed C/C has the lowest friction coefficient and the highest wear resistance.
(2) Dispersion of some ceramic particles into C/C composite was useful in improving its friction and wear properties, although some dispersions had the oppsite effect.
(3) Dispersion of ceramic particles with higher hardness than dross but lower hardness than sialon ceramics into C/C composite was found to improve both the fricition and wear properties of the composite.
