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