The　objective　of　this　study　is　to　prepare　CNT/AlSi10Mg　composites　using　mechanical　ball　milling　combined　with　SPS.　The　study　investigates　the　influence　of　ball-milling　time　and　CNT　content　on　the　mechanical　and　corrosion　resistance　of　the　composite.　This　is　performed　to　address　the　challenge　of　CNTs　dispersion　and　to　understand　how　CNTs　impact　the　mechanical　and　corrosion　resistance　of　the　composites.　The　morphology　of　the　composites　was　characterized　using　scanning　electron　microscopy　(SEM)　transmission　electron　microscopy　(TEM)　and　Raman　spectroscopy,　and　the　mechanics　and　corrosion　resistance　of　the　composite　materials　were　tested.　The　results　demonstrate　that　the　uniform　dispersion　of　CNTs　can　significantly　enhance　both　the　mechanical　properties　and　corrosion　resistance　of　the　material.　Specifically,　when　the　ball-milling　time　was　8　h,　CNTs　were　uniformly　dispersed　in　the　Al　matrix.　The　CNT/AlSi10Mg　composite　shows　the　best　interfacial　bonding　when　the　mass　fraction　of　CNTs　is　0.8　wt.%,　with　a　tensile　strength　of　−256　MPa.　This　is　69%　higher　than　the　original　matrix　material　without　the　addition　of　CNTs.　Moreover,　the　composite　exhibited　the　best　corrosion　resistance.　©　2023　by　the　authors.
