【 摘 要 】

In this present work, systematic study has been conducted to investigate the wear phenomenon by adding micron size silicon carbide and graphite particles into Al6061 base. Al6061 compound was taken as the base lattice to which SiC and graphite particulates were utilized as fortifications. 6 wt. % of SiC and 6 wt. % of graphite were introduced to the base framework. The micostructural behaviour was analysed through scanning electron microscopy, which uncovered the uniform appropriation of SiC and graphite content in the Al matrix. Pin-on-disc equipment was utilized to assess the volumetric wear loss of arranged samples, in which EN32 steel disc was utilized as the counter face. The outcomes uncovered that the volumetric wear misfortune was expanded with increment in applied load, disc speed and sliding distance for every one of the specimens. The outcomes additionally showed that the volumetric wear loss of the Al6061-6% SiC-6% graphite composite was smaller than the Al6061 lattice. The worn out surfaces were portrayed by SEM analysis.
