Abstract
The effects of electric potentials on the friction and wear behaviors of silicon carbide in aqueous solution were investigated. A pin-on-disc tester was modified to study SiC under the influence of electric potentials between -1 and +1 V (vs. Hg/HgCl). It was observed that both the friction coefficient and wear rates of SiC were decreased under the electric polarization. Friction coefficient was shown to be a function of potential and reached a maximum at the potential of open circuit potential (-260 mv Vs. Hg/HgCl).
