Wear Properties of High Volume Fraction SiC_P/Mg Composites Produced by Vacuum Pressure Infiltration

Abstract:

Magnesium matrix composites reinforced by SiC particles of different size have been fabricated by vacuum pressure infiltration to investigate the influence of volume fraction and particle size on wear properties. It was found that the wear resistance of SiC_p/Mg composites increased as volume fraction of particles with the same average diameter and reduced with the decrease of average diameter of particle, whereas the grooves furrow and adhesion increase. The influence of particle diameters on wear resistance was more prominent than that of volume fraction. The wear mechanism of composite and matrix alloy were oxidation, adhesive and delamination wear.
