Abstract
The microstructure and tribological performance of compositionally and functionally graded Al–Mg/AlB 2 metal–matrix composites (MMCs) produced by centrifugal casting have been investigated using Al–2wt.%Mg alloys containing 1, 2, 3, and 4 wt.% boron. Significant enrichment of aluminum diboride particles was observed in the external zone of the casting in the radial direction of the centrifugal caster. A corresponding increase in surface hardness as well as smaller wear volume in pin-on-disk wear tests were observed. The process provides a viable approach for lightweight, high wear resistance aluminum alloy components, particularly those with axial geometries.
