Mg-4.0Zn alloy composite reinforced by NiO-coated CNTs (NiO@CNTs) was synthesized by combining ball-milling and a casting process.The yield strength (YS) and elongation to failure of the composite were dramatically increased by 44.9％ and 38.6％,respectively,compared to its alloy counterpart.The significantly enhanced mechanical properties of the as-synthesized composite are mainly ascribed to an improved interfacial bond,grain refinement and good dispersion of CNTs in the matrix via.coating NiO on CNTs.It is shown that the NiO-nanolayer on the CNTs significantly enhances the interfacial bonding strength and effectively prevents the agglomeration of CNiTs.NiO@CNTs are,therefore,expected to be a highly sustainable and dispersible reinforcement for magnesium matrix composites with superior performance.
