Wear of A356/Al2O3 nanocomposites and optimisation of material and operating parameters
Apstrakt
The aim of this study was optimization of wear of nanocomposites with A356 alloy as a matrix. Different percentages of Al2O3 particles (0.2, 0.3 and 0.5 wt. %), with two average size (25 and 100 nm), were dispersed in the A356 matrix and fabricated by compocasting process. The tribological tests were conducted by the orthogonal L24 matrix. By application of the RSM method, a mathematical model was developed that best describes wear dependence on the observed factors and it was found that all considered factors have a significant impact on the wear of nanocomposite.
