The friction and wear behaviors of Si3N4/GCr15 were studied on the pin-on-disk machine under three different lubrication conditions. The results showed that both the friction and the wear were significantly lower in glycol than in deionized water and kerosene. The steady friction coefficient was 0.02 in glycol, 0.05 in deionized water and 0.20 in kerosene. Scanning electron microscopy revealed that formation and dissolution of the film may occur in deionized water and glycol. The main wear mechanisms were tribochemical and abrasive wear in deionized water, fretting wear for tribochemical film by esterification of oxidized surface of Si3N4 in glycol, corrosive and adhesive wear in kerosene.
