“…Enhanced corrosion, tribological, and mechanical properties were the main research focus of the automotive and aerospace industries in the 1970s-1990s, leading to significant technological advancements. In the early 2000s, some of the focus started to shift to electrical components and electronic devices [5][6][7][8][9][10]. As the accessibility of nanoparticles continues to rise, the interest in reduced cost and low-temperature electrodeposited MMCs continues to escalate [2].…”

“…For instance, electroplating has found a niche in microelectromechanical systems (MEMS) because the process can deposit different alloys onto depressed and oddly shaped geometric substrates [5,6,10,45]. Cu-Ni coatings have been evaluated for use as inert anodes in the fabrication of aluminum because of their enhanced electrical and thermal conductivity [8,9]. In marine environments, copper alloys are used to defend against biofouling of materials by inhibiting microbial-induced corrosion (MIC) [47][48][49][50].…”

The electrodeposition of Cu-Ni incorporated with nano-to microparticles to produce metal matrix composites has been reviewed in this chapter. The inclusion of particles into the metal matrix produced enhanced properties in the areas of electronics, mechanics, electrochemistry, and corrosion. In electronics, an increase in the magnetic properties and durability for microactuators was observed. Measurements of the mechanical properties showed an increase in hardness, wear resistance, shear adhesion, and tensile strength for the material. The corrosion resistance of the metal matrix coatings was improved over that of pure Cu-Ni. As the accessibility of nanoparticles continues to increase, the interest in reduced cost and low-temperature electrodeposited metal matrix composites continues to rise. However, only a small number of articles have investigated Cu-Ni composite coatings; these composite coatings need further examination due to their advantageous properties.

“…The previous studies have found that it is necessary to ensure the content of 25wt% Cr or more in the alloy in order to form the continuous and protective scales of chromia on Fe-NiCr alloy surface in high temperature oxidation process [13]. In fact, higher content of Cr in the alloy may increase its brittleness [14].…”

Fe-40Ni-15Cr alloys with different grain size were prepared by powder metallurgy (PM) and mechanical alloying (MA) through hot pressing technique. Their oxidation behavior was examined at 1073-1173 K in 1.01 10 2 kPa pure oxygen. Results show that the oxidation kinetics of the coarse grained PMFe-40Ni-15Cr and nanocrystalline MAFe-40Ni-15Cr alloys deviates from the parabolic law and their instantaneous parabolic rate constants change with time irregularly. At 1073 K, mass gain of MAFe-40Ni-15Cr alloy is lower than that of PMFe-40Ni-15Cr alloy. At 1173 K, mass gain of MAFe-40Ni-15Cr alloy is higher than that of PMFe-40Ni-15Cr alloy for initial 4 h and afterwards becomes lower than that of PMFe-40Ni-15Cr alloy up to 24 h. PMFe-40Ni-15Cr alloy formed iron oxide scales, while MAFe-40Ni-15Cr alloy formed the continuous and protective scales of chromia on the alloy surface at 1073-1173 K. The reason may be that grain refinement caused the increment of the grain boundary which leads to the faster diffusion of the reactive component Cr from the alloy to alloy/scale interface. Finally, MAFe-40Ni-15Cr alloy formed the continuous and protective scales of chromia.

Nanocrystallization, an alternative method for improving the high-temperature oxidation resistance of alloys by increasing the supply of the protective oxide-forming element such as Cr or Al, has received considerable attention. However, for nanocrystalline ͑NC͒ alloys containing two phases, the effect of spatial distribution uniformity of the oxide-forming element on oxidation has not been studied. In this contribution, three compositionally similar Cu-Ni-Cr NC alloys, with corresponding Cr distribution in atomic, nano-, and micrometer length scale, have been specifically designed and fabricated using direct current magnetron sputtering ͑DCMS͒, nanocomposite electrodeposition ͑NCE͒, and surface mechanical attrition treatment ͑SMAT͒, respectively. These NC alloys, in comparison to the conventional coarse-grained alloy counterpart during oxidation in air at 800°C, exhibited dramatically increased ability to develop a continuous chromia scale, causing a considerable decrease in the oxidation kinetics. The change in oxidation behavior is associated not only with the small grain size of the alloys, but also with the refined distribution of the Cr-rich phases. Among the three methods, microstructures developed by DCMS and NCE were more effective than that from SMAT. The formation of these processing-dependent microstructures and their relationship with the Cr-selective oxidation process are discussed.
