| Abstract: | One kind of three-dimensional network structure, reinforced aluminum magnesium matrix composites, has been prepared by pressure-assisted
and vacuum-driven infiltration technology. The composites interpenetrated with ceramic have higher wear resistance than the
metal matrix owing to their special topology structure. The reinforcement volume fraction has a large effect on abrasive wear.
The wear rate decreases with the increase of the volume fraction of reinforcement and increases with the increase of sliding
time and applied load. The wear mechanism of the composites (abrasive wear) differs greatly from the matrix alloy (adhesive
wear). |
