Study on the Friction Properties of Porous Al₂O₃ Ceramic/ Al₂O₃ Ultrafine Particle/ Epoxy New Composites

Abstract:

Porous Al₂O₃ ceramic/Al₂O₃ ultrafine particle/epoxy new composites were fabricated using the ordered Al₂O₃ porous ceramic as the frame. The effects of three-dimension interpenetrated Al₂O₃ ceramic, load, and sliding velocity on friction coefficient and wear rate of the composites were studied. The results showed the new composites had better wear resistance compared with Al₂O₃ ultrafine particle/epoxy composites. The friction coefficient and wear rate of new composites with the porous Al₂O₃ ceramic frame of 16.8% were 0.32 and 0.76×10^-6 mm³/N^-1m^-1, respectively. The new composites had stable friction coefficient and low wear rate with the change of load and sliding velocity, which is due to the porous Al₂O₃ ceramic frame as undertaker of load during friction process.
