“…They proposed that the galvanic corrosion between α -Mg matrix and CNTs was relieved by the concentration of Al atoms around CNTs via heat treatment. This phenomenon caused the reduction of surface potential difference (SPD) between α -Mg matrix and CNTs [ 11 ]. Huang et al studied the galvanic corrosion behavior of Inconel 718 after electron beam welding.…”

Ti and solution treated Mg alloys such as AZ31B (ST), AZ61 (ST), AZ80 (ST) and AZ91 (ST) were successfully bonded at 475 °C by spark plasma sintering, which is a promising new method in welding field. The formation of Ti3Al intermetallic compound was found to be an important factor in controlling the bonding strength and galvanic corrosion resistance of dissimilar materials. The maximum bonding strength and bonding efficiency at 193 MPa and 96% were obtained from Ti/AZ91 (ST), in which a thick and uniform nano-level Ti3Al layer was observed. This sample also shows the highest galvanic corrosion resistance with a measured galvanic width and depth of 281 and 19 µm, respectively. The corrosion resistance of the matrix on Mg alloy side was controlled by its Al content. AZ91 (ST) exhibited the highest corrosion resistance considered from its corrode surface after corrosion test in Kroll’s etchant. The effect of Al content in Mg alloy on bonding strength and corrosion behavior of Ti/Mg alloy (ST) dissimilar materials is discussed in this work.

“…The resistance to the transfer of charge (R ct ) value, also known as the barrier that the passive layer offers for the transport of charge, may be used to assess the efficacy of the passive layer in this situation. 37,38 Greater R ct values suggest that more excellent corrosion resistance is attained by decreased ion movement in the passive layer during the deterioration operation. As shown in Fig.…”

“…Table 2 depicts the corrosion characteristics of the fabricated Mg/CNT composites. Funatsu et al [149] attempted to examine the corrosion behavior of developed AZ61B-based CNT-reinforced composites through the PM route. In the experimentation, they employed thermal treatment of 823 K for the duration of 10 h while introducing Al atoms into the fabricated composites, resulting in an accumulation of Al atoms adjacent to the CNTs' surface.…”

Properties such as superior specific strength, being imponderous, and the ability to reprocess are the key features that have drawn attention to magnesium. In the last few years, applications such as automotive, aerospace, and medical applications have been seeking light-weight equipment, and light-weight materials are required for making them. These demands were matched by developing metal matrix composites with magnesium as a base and reinforced with carbon nanotubes (CNTs), grapheme nanoplatelets (GNPs), or ceramic nanoparticles. CNTs have been adopted for developing high-strength metal matrix composites (MMCs) because of their delicately superior thermal conductivity, surface-to-volume ratio, and tensile strength, but lower density. In developing high-performance light-weight magnesium-based MMCs, a small number of CNTs result in refined properties. However, making Mg-based MMCs has specific challenges, such as achieving uniform reinforcement distribution, which directly relates to the processing parameters. The composition of CNT, CNT sizes, their uniform distribution, Mg-CNT interfacial bonding, and their in-between alignment are the characteristic deciding factors of Mg-CNT MMCs. The current review article studies the modern methods to develop Mg-CNT MMCs, specifications of the developed MMCs, and their vital applications in various fields. This review focuses on sifting and summarizing the most relevant studies carried out on the methods to develop Mg-CNT metal matrix composites. The article consists of the approach to subdue the tangled situations in highlighting the Mg-CNT composites as imminent fabrication material that is applicable in aerospace, medical, and automotive fields.
