Research on Frictional Material Prepared by Copper-coating Al_2O_3 Particles on Iron-based
The Al2O3 iron-based frictional material was prepared by powder metallurgy. Al2O3 particles were coated with copper through electroless plating method. The friction coefficient and abrasiveness of Al2O3 reinforced iron-based frictional material prepared by powder metallurgy were tested. The effects of interface combination mode between reinforcement and substrate, friction and wear mechanism on iron-based frictional material were studied. The results show that the friction and wear properties were all enhanced after Al2O3 is coated with copper.
