Wear resistance of graphite/aluminium composites that prepared by stirring casting
The graphite reinforced aluminum matrix composites were prepared by using stir-casting in this paper,with bulk alloy of ZL111,reinforcement of graphite particles coated with oxide,and the friction behavior was investigated perfectly.The results indicated that,the aluminum matrix composites reinforced with 6 wt.% graphite particles coated with oxide have a good property of self-lubrication under the condition of dry friction with a pressure of 40 N,a relative rate of 2.62 m/s of frictional backing gear,a wear time of 60 min,in addition,the friction factor and the wear capacity of the graphite/aluminum matrix composites were less than those of bulk alloy.Moreover,the friction factor and the wear capacity of the graphite / aluminum matrix composites decreased with an increase in mass fraction of the graphite coated with oxide,and the friction factor of composites became bigger while the fraction of the graphite particles was over 6wt.%.
