“…CNTs can slow down the formation of oxide layer and keeps the layer detached from the alloy. Moreover, the addition of CNT has made the composite more noble by shifting the E corr to more positive values 15 . Also the increase in percentage of CNTs leads to the primary passivation potential starting toward nobler values.…”

Carbon nanotubes (CNTs) reinforced aluminum matrix composites were fabricated using powder metallurgy technique. The effect of nanotubes content on mechanical properties of the composites was investigated. Experimental results showed that nanotubes are homogeneously distributed in the composites. The corrosion of AA 4032 alloy based nanocomposite with CNTs was investigated by electrochemical polarization studies. CNTs‐reinforced composites have shown a better corrosion resistance than parent alloy. The nanotubes content significantly affect mechanical and corrosion properties of composite.

“…The improvement in mechanical properties was attributed to grain refinement resulting in inhibition of grain growth resulting from the interlocking of CNTs [ 71 , 75 ]. Endu et al [ 76 ] prepared AZ91/MWCNTs composites by a process including powder blending, and then vacuum controlled HPS and extruding processes. The researchers showed that the filler in the Mg-based matrix could considerably enhance the corrosion resistance.…”

In recent years considerable attention has been attracted to magnesium because of its light weight, high specific strength, and ease of recycling. Because of the growing demand for lightweight materials in aerospace, medical and automotive industries, magnesium-based metal matrix nanocomposites (MMNCs) reinforced with ceramic nanometer-sized particles, graphene nanoplatelets (GNPs) or carbon nanotubes (CNTs) were developed. CNTs have excellent material characteristics like low density, high tensile strength, high ratio of surface-to-volume, and high thermal conductivity that makes them attractive to use as reinforcements to fabricate high-performance, and high-strength metal-matrix composites (MMCs). Reinforcing magnesium (Mg) using small amounts of CNTs can improve the mechanical and physical properties in the fabricated lightweight and high-performance nanocomposite. Nevertheless, the incorporation of CNTs into a Mg-based matrix faces some challenges, and a uniform distribution is dependent on the parameters of the fabricating process. The characteristics of a CNTs reinforced composite are related to the uniform distribution, weight percent, and length of the CNTs, as well as the interfacial bonding and alignment between CNTs reinforcement and the Mg-based matrix. In this review article, the recent findings in the fabricating methods, characterization of the composite’s properties, and application of Mg-based composites reinforced with CNTs are studied. These include the strategies of fabricating CNT-reinforced Mg-based composites, mechanical responses, and corrosion behaviors. The present review aims to investigate and conclude the most relevant studies conducted in the field of Mg/CNTs composites. Strategies to conquer complicated challenges are suggested and potential fields of Mg/CNTs composites as upcoming structural material regarding functional requirements in aerospace, medical and automotive industries are particularly presented.

“…The literature contains many investigations into the mechanical and tribological properties of metal matrix composites with carbon-based reinforcements. For example, Endo et al [6] characterized the mechanical properties of CNT-magnesium composites using a field emission scanning electron microscope (FE-SEM) and showed that CNT addition increased the elastic modulus and tensile strength of the magnesium matrix by around 25% and 11%, respectively. Sun et al [7] showed that CNT addition improves both the tensile strength and the fracture strain of pure nickel.…”
