Structure, microstructure and corrosion properties of brush-plated Cu–Ni alloy

Abstract

Cu-Ni alloy coatings on copper substrate by the brush-plating process have been investigated using XRD and AFM. The X-Ray diffraction analysis revealed that the brush-plated Cu-Ni alloy was heterogeneous and composed of cubic Cu 3.8 Ni phases. Uniform surface coverage of the substrate by granular morphology was observed from AFM. The corrosion protection performance of the brush-plated Cu-Ni alloy on copper substrate has been assessed using electrochemical corrosion tests. These results indicated a high charge transfer and low I corr for the alloy system compared with copper deposits and the copper substrate.

Wafer-scale few-layer graphene growth on Cu/Ni films for gas sensing applications

“…From this, the measured interplanar distance (d) is found to be 0.21 nm. The (111) interplanar distance is close to that of a Cu 3.8 Ni alloy, d (111) =0.208 nm [43]. This result agrees with the XRD and indicates the formation of a Cu-rich Cu-Ni alloy (Fig.…”

Preparation of Nanocrystalline Cu Films by Brush-Plating

“…However, it is noted that electric brush-plating technique are mainly applied to repairing or coating the surfaces of work-pieces, and are less used for the preparation of nc metals and metal film materials [14,15]. In this paper, we report the preparation of nc Cu films by…”

Surface stability and electronic structure of CuNi alloy (111) as a potential catalyst for graphene growth-a density-functional theory study

“…We choose (111) plane because it has more active sites, which can improve catalyst performance [14,19]. Based on experiments, bulk CuNi frequently appears in the L10-type tetragonal crystal structure with the composition ratio of Cu and Ni being 1:1, as shown in Figure 1 [20]. Therefore, we start this study by optimizing the structural properties of bulk CuNi and getting the lattice parameter of 𝑎=𝑏=3.550 Å and 𝑐=3.591 Å.…”
