Studies on mechanical and dry sliding wear of A16061-SiC composites

摘要

Particulate reinforced Al-MMCs exhibits better mechanical properties and improved wear resistance over other conventional alloys. In the present paper, the experimental results of the mechanical and tribolog ical properties of A16061-SiC composites are presented. The composites of A16061 containing 2-6 wt% SiC were prepared using liquid metallurgy route. The experimental results showed that the density of the composites increase with increased SiC content and agrees with the values obtained through the rule of mixtures. The hardness and ultimate tensile strength of A16061-SiC composites were found to increase with increased SiC content in the matrix at the cost of reduced ductility. The wear properties of the com posites containing SiC were superior to that of the matrix material.
