摘 要：To verify the effect of Al2O3 particle content and size as an abrasive on resin matrix friction materials for mining equipment, the tribological performance of friction materials was studied by using a blockon-ring tribotester over a wide range of applied load and sliding speed. The testing conditions simulated brake conditions of mining equipment. The antiwear property of nano-Al2O3 was superior to that of micro-Al2O3 for friction materials. The friction coefficients of specimens increased with the increase of nano-Al2O3 content. The wear rates decreased with increasing nano-Al2O3 content. The wear rates of specimens containing nano-Al2O3 was about 2-8 times lower than that of specimen with micro-Al2O3. The specimen with 10.5 vol% nano-Al2O3 showed the best tribological properties. The wear mechanism of specimens with nano-Al2O3 was abrasive wear and plastic deformation.
