Effect of Dry Sliding Wear Behaviour of AA6061/ZrB2/SiC Hybrid Composite.

This paper investigates the dry sliding wear behaviour of AA6061/ZrB2/SiC hybrid composite prepared by the stir casting. A pin-on-disc wear apparatus was used for this study. The effect of ZrB2 and SiC particulate content and normal load on wear rate was analyzed. The insitu fabricated ZrB2 and the reinforced SiC particles enhance the wear resistance of the AA6061 composite. The worn surface analysis of the composite as a function of ZrB2 and SiC particulate content and normal load are also presented. [ABSTRACT FROM AUTHOR]
