This study aimed at effects of mechanical properties and microstructure of 2024Al/10SiC/xGr (x=1,3,5vol/%) composites on wear characteristics.
Tensile test, hardness test and wear test were conducted for the evaluation of mechanical properties such as hardness and tensile test.
Wear characterisstics were measured by wear loss, friction coefficients, and friction temperature rise.
The experimental results indicate that the maximum hardness was found at aging condition of 190℃ and 14 h.
The tensile strength decreased, but the wear resistance increased by adding graphite contents.
The wear surfaces of the specimens and the counter steel were observed and analyzed by OM, SEM, EDS, and mechanical properties.
The worn volume has been measured as a function of the alloy composition, slidilng distance, normal load and sliding velocity.
Optical and scanning electron microscopic examinations of the test specimen, were track and wear debris have been carried out for the elucidation of the wear mechanism.
