“…4 SiC, 5 TiC, 6 Al 2 O 3 7 are most preferred micro-size particles as reinforcement for magnesium matrix composites. In recent years, multi-wall carbon nanotubes (MWCNTs) 8 and graphene 9 have become popular because of their excellent mechanical and physical properties. Graphene which has 1 TPa elastic modulus and 125 GPa fracture strength 10 is known as a single atomic monolayer of graphite.…”

The present study aims to investigate the effect of Multi-Wall Carbon Nanotube on dry sliding and corrosive wear performance of pure magnesium. Multi-wall carbon nanotube reinforced composites with different weight fractions (0.25 wt.% and 0.5 wt.%) were fabricated by semi powder metallurgy. Hardness test was performed for all samples. To evaluate wear performance of the samples, three different loads (10 N, 20 N, and 40 N) were applied at the room temperature in both dry and 3.5 wt.% NaCl corrosive environments. Worn surfaces and microstructures of the samples were characterized using Scanning Electron Microscope. Results show that carbon nanotubes embedded in the matrix without any macro-defects. The hardness of pure magnesium was improved with the addition of multi-wall carbon nanotube considerably. 0.5 wt.% multi-wall carbon nanotube reinforced composite exhibited best wear performance both in dry and corrosive conditions.

“…The AZ31 aluminum alloy reinforced with CNTs exhibited a significant increase in wear compared to the currently available alloys [1]. Addition of 2.0 wt% of CNTs to the 2024 aluminum alloy led to a considerable grain refinement, but shortening of CNTs occurred during the ball-milling process [2]. Independently reinforced n-Al2O3 composites showed a lower wear rate than independently reinforced CNTs; however, its coefficient was higher [3].…”

Aluminum alloys play a major role in the aircraft, shipbuilding, and automotive industries because of their superior strength-to-weight ratio. The aluminum alloy 5083 0 has been used in the shipbuilding industry due to its corrosion resistance properties wants is a nanoparticle that has unique properties based on its structure . Moreover, the presence of carbon results in a very high wear resistance. Its high tensile strength along with its good electrical properties makes it a desirable reinforcement for aluminum alloys. Friction stir processing is a solidstate processing technology that has acquired significant attention in recent years because of the solid-state processing wherein the mixing of materials takes place in the plastic state. This removes the disadvantages of liquid-state processing such as casting, which occurs in high temperatures and leads to various defects, in turn reducing the strength of the composites. These were the motivation behind the current study. In the present study, MWCNTs were reinforced in the magnesium-based aluminum alloy 5083 0. This study exploits the presence of carbon as a self-lubricating feature.

“…The utilized torsion or frictional force produced in the FSW process can cause the welding of the CNT and metal together for fabricating the CNT-reinforced metal matrix [ 32 , 101 ]. Based on the observation of microstructure, the main reasons for the acceptable AZ31/MWCNT composite surface hardness produced by the FSP process could be high interfacial bonding between the MWCNT reinforcement and AZ31 magnesium alloy matrix as well as the fine grain size [ 102 ]. Morisada et al [ 32 ] utilized the FSP process for fabricating an Mg/CNTs composite.…”

“…A remarkable enhancement was seen in wear resistance of MWCNT-reinforced AZ31 Mg–alloy composite fabricated by FSP, comparing with that of unreinforced AZ31 alloy. Homogenous distribution of MWCNTs reinforcement in the matrix, grain refinement, and high interfacial bonding at the MWCNTs and AZ31 matrix interface was claimed as the reasons for the achieved enhancement of the mechanical properties [ 102 ]. Selvamani et al [ 99 ] investigated the wear behavior of AZ91D-CNTs nanocomposites fabricated by the stir casting process.…”

“…Some CNTs reinforcement particles in this sample, with comparatively higher loading of CNTs, may be agglomerated and act as plowing tools for the material and result in abrasive wear. The mechanism of three-body abrasion happens when an adequately hard particle is trapped between two surfaces which one of them, or both could be abraded by the particle [ 102 ]. This wear mechanism could occur under any conditions of loading and could occur at the same time with all other wear mechanisms [ 148 ].…”

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.
