Produktbeschreibung

In the present work, the dry sliding wear behavior of Al-12wt%Si matrix nanocomposites reinforced with various amounts of 2, 4 and 6 wt% (Al2O3 + TiO2) nanoparticles as hybrid addition is investigated.All samples were prepared by powder metallurgy by mechanical milling of the base alloy (Al-12%Si) powder and added the hybrid nanopowders of (Al2O3 +TiO2), followed by cold pressing at (100 bar) and sintering at (520 oC) for (90 min). X-ray diffraction analysis was performed to identify the phases in the mixed powders.AFM, SEM were used to investigate the morphology of mixed powders and some nanocomposites samples. Results AFM images of mixed powders for the base alloy and hybrid nanopowders (Al2O3 + TiO2) indicate good mixing between the different micro and nano powders and homogenous distribution of nanopowders in the Al-Si matrix.Results indicate that the wear resistance of the nanocomposite is considerably improved by addition of the reinforcement nanoparticles and the wear ratedecreases with increasing the weight percentages from 2 to 6wt% (Al2O3+TiO2) hybrid nanoparticles in matrix of Al-alloy.The important applications in space equipment
