“…In the case of CNT/Al composites, the metallic salts decompose in the electrochemical cell and release metallic ions to form CNT composites. [93,94] The CNTs can be deposited in an uniform manner on a substrate or by codeposition of metal and CNTs on a conductive substrate. The latter one is the most commonly used technique in electrochemical deposition.…”

Herein, the investigations conducted in the area of aluminum (Al) matrix composites reinforced with carbon nanotubes (CNTs) are presented. The application of CNT reinforcement in Al alloys is driven by its exceptional chemical and mechanical properties. The critical issues in the processing techniques, challenges in the interfacial mechanisms between the Al matrix and CNTs, and strengthening effects due to the presence of reinforcements are reviewed. The mechanical properties of CNT/Al composites are found to be effectively enhanced with an addition of CNTs even at a small amount. The extent of strength improvements depends mainly on the dispersion of CNTs in the matrix and interfacial bonding between the matrix and CNTs. Limited theoretical modeling can predict the properties of CNT/Al composites to some extent, but without considering the detailed processing parameters. Based on the gaps identified here, future research directions are suggested, including the relationships between the processing parameters and micro-and nanostructures, and multiscale mechanical modeling and simulation, aiming to further understand the strengthening mechanisms and develop advanced CNT-reinforced Al and other metal composites for critical engineering applications.

“…The macro-cracks, which are known as solidification cracks, often are generated near the solidification temperature range [ 85 ]. They are caused by the insufficient supplement of liquid metal when the consolidation and contraction process suddenly release stress after the increased thermal stress discharge from the rapid cooling process [ 86 , 87 ]. Micro-cracks mainly include phase interface cracking, slip zone cracking, and grain boundary cracking.…”

Owing to the unparalleled advantages in repairing of high value-add component with big size, fabricating of functionally graded material, and cladding to enhance the surface properties of parts, the laser material deposition (LMD) is widely used. Compared to the continuous wave (CW) laser, the controllability of the laser energy would be improved and the temperature history would be different under the condition of pulse wave (PW) laser through changing the pulse parameters, such as duty cycle and pulse frequency. In this paper, the research status of temperature field simulation, surface quality, microstructural features, including microstructures, microhardness, residual stress, and cracking, as well as corrosion behavior of metallic coating created by pulsed laser material deposition have been reviewed. Furthermore, the existing knowledge and technology gaps are identified while the future research directions are also discussed.

“…Among them, the gradual increase in R c means that from S1 to S4, the electrons in the sample become more difficult to move, which corresponds to a lower corrosion rate. [43] EIS is a nondestructive and sensitive method that can obtain information on the characteristics of the surface layer of the material and the corrosion mechanism in a specific environment. In the Bode plots (Figure 11a), the impedance modulus (|Z| ¼ (Z 02 þ Z 002 ) 0.5 ) of S4 is higher than that of S1.…”

In this article, a quasi‐continuous ratio gradient alloy steel (GAS) with a 24CrNiMo high‐strength low‐alloy steel matrix for high‐speed railway brake discs is fabricated by selective laser melting (SLM). The composition of GAS is X% 24CrNiMo + (1–X)% wear‐resistant stainless steel (WSS), in which X is 100, 65, 35, and 0. The relationship between the microstructure and the corrosion resistance is intensively studied by electron backscatter diffraction (EBSD) and potentiodynamic electrochemical equipment. With the increase in the content of WSS, the low angle grain boundaries of the GAS increases, and the microstructure refines and the texture intensity decreases. The passivation film of the external WSS strengthening layer is dense; the corresponding corrosion potential and corrosion current density are −0.109 V and 2.08 × 10−8 A cm−2, respectively. The corrosion current density is about 1% of the substrate 24CrNiMo, and the corrosion resistance of the material is significantly improved.
