“…The corrosion current density (Icoor) of CNTs/Cu composites is significantly lower than that of CuCr, which indicates that the existence of 3D interconnected structures and the addition of CNTs have a significant effect on slowing down the corrosion process. The protection efficiency (PE) is calculated from the measured Icorr value and equation (1) [41,42]:…”

AbstractIn this paper, the 3D pore structure of CuCr powders were obtained by pre-press shaping process, and finally the 3D interconnected carbon nanotubes/copper (CNTs/Cu) composites with excellent properties were insitu synthesized by chemical vapor deposition (CVD) and spark plasma sintering (SPS) technique. The morphology and structure of CNTs/ Cu composites are characterized by scanning electron microscopy (SEM), Raman spectra, transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), and the results showed that the quality of CNTs and the interfacial bonding strength of CNTs/ Cu composites can be improved owing to the 3D pore structure. Meanwhile, the 3D pore structure was favorable to avoid pollution of CNTs during the synthesis process. The tensile strength of CNTs/ Cu composites increased to 421.2 MPa, with 47.6% enhancements compared to CuCr. Furthermore, the coefficient of friction (COF) reduced to 0.22 and the corrosion resistance were increased by 51.86% compared to CuCr. Consequently, our research provides a novel and an effective method for the synthesis of high quality CNTs/ Cu composites.

“…Moreover, a considerable decrease in the wear rate of both Ni-P [4] and Ni [5] coatings was observed, ascribed to the presence of loose CNTs between the surfaces in contact, released during initial stages of the wear test, which prevent their intimate contact. On the other hand, Cu-CNT composites have been the focus of several investigations for a while [4,[23][24][25][26][27][28][29][30][31]. Pure copper coatings have been mainly used for protective and decorative purposes due to their good corrosion resistance and appearance, as well as in electrical or electronic applications due to copper's high electrical and thermal conductivities.…”

“…Reinforcement of copper with CNTs seems to be a promising approach since, besides the extraordinary mechanical properties previously mentioned of these particles, they have high thermal and electrical conductivities [24,30] and could act as weight reducers [31]. For these reasons, many researchers have devoted their efforts to preparation of Cu-CNT composites, using either by powder metallurgy [4,23] and electrocodeposition [24][25][26][27][28][29].The resulting materials presented reasonable thermal and electrical conductivities and enhanced microhardness and tribological performance. Nevertheless, wear resistance and COF measurements have only been carried out on samples prepared by the former technique, and no information regarding the tribological properties of electrodeposited Cu-CNT coatings is available.…”

Self-lubricating coatings have been studied for a long time due to their convenience compared to systems which need periodic lubrication. For this reason, Cu-CNT composite coatings with high wear resistance and low coefficient of friction were obtained by electrodeposition from an ecofriendly alkaline glutamate-based electrolyte. Deposition experiments were performed at various experimental conditions in the presence of lowfrequency ultrasound agitation to ensure particle dispersion and enhance their incorporation in the Cu matrix. Moreover, the effect of 2-Butyne-1,4-diol (an additive use in glutamate-based formulations) on coatings mechanical and tribological properties was assessed. Both pure Cu and Cu-CNT were obtained under all the experimental conditions considered and later characterized by SEM and XRD. Finally, pin-on disk tests were performed to estimate the coefficient of friction and determine the wear resistance. The results showed that incorporation of CNT to the copper matrix led to an improvement of the tribological performance of pure Cu, regardless of deposition parameters. Furthermore, it was found that 2-Butyne-1,4-diol had a strong influence on deposit microhardness and tribological performance, as a result of the changes in microstructure induced by this additive which promoted the development of a (111) texture. Likewise, the incorporation of particles to the Cu matrix promoted changes in surface morphology as well as in the preferred crystalline orientation, promoting crystal growth along the [311] direction. The results indicate that this simple and cheap methodology is suitable for fabrication of self-lubricating coatings.

“…The first report on the preparation of a composite coating through electrodeposition in 1928, 25 triggered a large number of investigations devoted either to the development of these materials or the understanding of the underlying phenomena. Several metal-particle systems have been considered so far, 6,7,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] of which Cu-based composites are the ones that have attracted the most interest. 33,[45][46][47][48][49][50] The latter is due to copper's good corrosion resistance, appearance and high thermal and electrical conductivity, and the possibility to improve its mechanical properties by the incorporation of particles in the deposit.…”

Electrodeposition of Cu-SiO 2 composite coatings from an alkaline non-cyanide electrolyte containing glutamate as complexing agent was studied. Silica mesoporous particles were synthesized using a modified Stöber methodology, and later their surface chemistry was changed by functionalizing them with 3-aminopropyltriethoxysilane. Particles microstructure and morphology were characterized (SEM, TEM, XRD) and their charging behavior in several electrolytes was studied through ζ -potential measurements. Galvanostatic deposition was performed in electrolytes containing both as-prepared and functionalized SiO 2 at various current densities, and the influence of ultrasonic irradiation (37 Hz) was evaluated. For some experiments, 1.5 g L − of Polyquaternium 7 were added to the solution. SEM and XRD were used to characterized coatings morphology and microstructure, whereas EDS was used to estimate SiO 2 wt%. The results showed that the effect of ultrasound on the codeposition process depends on current density and particle surface chemistry. All the trends observed in this study could be explained taking into account ζ -potential values recorded and previously reported theories. Adjusting the experimental conditions, it was possible to obtain deposits with SiO 2 contents of ≈5 wt%. Finally, it was found that both ultrasonic irradiation and Polyquaternium 7 affect the morphology and crystal orientation of the deposits.
