“…Similarly, Zhai et al [167] studied the EBM fabrication of a NAB alloy (81.1Cu-9.5Al-4.2Ni-4.0Fe-1.2Mn) and found similar results to those reported by Lu et al [166]. They also reported the formation of a high-density part (>99%) containing a homogeneous microstructure with equiaxed grains and uniformly distributed (Fe,Ni)Al precipitates, which collectively resulted in isotropic mechanical properties.…”

Copper-based materials have long been used for their outstanding thermal and electrical conductivities in various applications, such as heat exchangers, induction heat coils, cooling channels, radiators, and electronic connectors. The development of advanced copper alloys has broadened their utilization to include structural applications in harsh service conditions found in industries like oil and gas, marine, power plants, and water treatment, where good corrosion resistance and a combination of high strength, wear, and fatigue tolerance are critical. These advanced multi-component structures often have complex designs and intricate geometries, requiring extensive metallurgical processing routes and the joining of the individual components into a final structure. Additive manufacturing (AM) has revolutionized the way complex structures are designed and manufactured. It has reduced the processing steps, assemblies, and tooling while also eliminating the need for joining processes. However, the high thermal conductivity of copper and its high reflectivity to near-infrared radiation present challenges in the production of copper alloys using fusion-based AM processes, especially with Yb-fiber laser-based techniques. To overcome these difficulties, various solutions have been proposed, such as the use of high-power, low-wavelength laser sources, preheating the build chamber, employing low thermal conductivity building platforms, and adding alloying elements or composite particles to the feedstock material. This article systematically reviews different aspects of AM processing of common industrial copper alloys and composites, including copper-chrome, copper-nickel, tin-bronze, nickel-aluminum bronze, copper-carbon composites, copper-ceramic composites, and copper-metal composites. It focuses on the state-of-the-art AM techniques employed for processing different copper-based materials and the associated technological and metallurgical challenges, optimized processing variables, the impact of post-printing heat treatments, the resulting microstructural features, physical properties, mechanical performance, and corrosion response of the AM-fabricated parts. Where applicable, a comprehensive comparison of the results with those of their conventionally fabricated counterparts is provided.

“…Besides the reduction of room temperature brittleness and improvement of high‐temperature strength, the enhancement of the characteristics can be achieved with the addition of alloying elements such as Yttrium (Y), [ 9 ] Vanadium (V), [ 10 ] Chromium (Cr), [ 11 ] and Ferrum (Fe). [ 12 ] Several studies declare that Cu atoms possessed a propensity to substitute for atomic site of Ni atoms in Al‐rich alloys, while Cu atom is prone to replace the site of Al atom for Ni‐rich alloys. This behavior is also evident in NiAl alloys.…”

Intermetallic compounds with special physical and chemical properties are considered to be advanced materials. However, the brittleness at room temperature of intermetallic compounds leads to poor performance, which limits its widespread application in engineering. The objective of this study is to investigate the strengthening mechanism of the copper (Cu) on the microstructure and material performance of WC/NiAl/TiC composite coatings by the laser cladding process. The results reveale that Cu element has a significant effect on the microstructure evolution of the coatings by inhibiting coarse crystal formation. The refined microstructure of the layer had been realized. X‐ray diffraction (XRD) analysis demonstrate a reduction in lattice spacing within the composite coating structure as the proper Cu is added. Furthermore, the addition of Cu contributed to an enhancement in microhardness (868.9 HV0.2) and wear resistance. With 3% copper been added, the wear loss of the coatings has been reduced by 81.13% and the average microhardness value has been increased by 1.4 times as well. Moreover, the chemical metallurgical bond is produced between the particles and bonding phase resulting in strengthened compactness within the layer acting as a physical barrier‐like film that increases polarization resistance.

“…Solid lubricants play a crucial role in the tribological properties of composites [6,22]. Researchers have conducted a lot of explorations from the types of lubricants and additives [23,24]. On the one hand, a variety of lubricants were mixed into multi-lubricants (WC/DLC/WS 2 , YSZ/Au/MoS 2 /DLC, YSZ/Ag/Mo-TiN, and SnAgCu, etc.…”

Wind power gears will be excessively worn due to lubrication failure during operation. Herein, the tribological properties of rubbing pairs are improved by filling solid lubricants into surface texture. In texture design, three types of topological textures (Circle (C), Hexagon (H) and Circle/Hexagon (CH)) were obtained by cell topology optimization, and then three cases with 20%, 30%, and 40% density were designed for each texture. Next, SnAgCu and TiC were deposited in texture of AISI 4140 steel (AS) to obtain 9 kinds of self-lubricating surfaces. Among them, AS with 30% CH density (AS-CH30) exhibits excellent mechanical and tribological properties. Compared with AS-C and AS-H, the maximum equivalent stress of AS-CH was decreased by 10.86% and 5.37%, respectively. Friction coefficient and wear rate of AS-CH30 were 79.68% and 78% lower than those of AS. The excellent tribological performances of AS-CH30 can be attributed to the synergistic effect of topological surface and solid lubricants. Topological surface can not only reduce fluctuation of equivalent stress, but also promote the stored lubricants to be easily transferred at the contact interface to form a 200 nm lubricating film containing solid lubricants (mainly), oxides and wear debris.
