Network ceramics reinforced aluminum matrix composites were successfully prepared by squeezing casting method

and wear behavior of the composites was examined in condition of dry friction.The results reveal that the wear resistance of the composites is greatly superior to that of the matrix alloy.Network ceramics can effectively inhibits or restrain the transformation of matrix alloy from mild wear to severe wear by subjecting to load as a result of concaving on wear surface as a supporter

meanwhile

it can disperse load to around direction to reduce the loss of matrix alloy on wearing surface resulting from plastic deformation.
