“…Since the density of the produced samples is almost the same (around 513.5 kg/m 3 , after the third phase), they show quite similar values for yield strength and deformation energy. As it can be seen from previous works [2,3], the yield strength of third phase specimen enhances up to 232% in comparison to base aluminum foam. To demonstrate the effects of graphene electrodeposition on aluminum foam mechanical strength, two samples were chosen with very similar starting weight and density, such as 211 kg/m 3 and 2.4 g. During electrodeposition, both samples were treated to obtain almost identical weight percentage change (DP%) in all phases.…”

“…The sacrificial anode used for the entire process was composed of two copper plates (75 · 76 · 15 mm) connected to each other to completely cover the sample, allowing the best possible results. The anode was thus also designed to make easily accessible that part of the aluminum sample, which is always above the The amount of GNP dispersed in solution and galvanic parameters used are the results of previous optimization works [2,3]. The baths were kept in agitation with a magnetic agitator, located inside the electrolytic cell.…”

“…The search for materials that conduct heat well has become essential for the design of the next generation of heat exchangers. Due to their advantageous characteristics, such as low production costs, wide potential window, high thermal conductivity and mechanical strength, inert electrochemistry [1], carbon materials have been widely used in many technological fields [2,3]. The advantages of carbon materials combined with those of nanostructured materials, such as carbon nanotubes [4,5], carbon nano-fibers [6], highly ordered mesoporous carbons [7,8], etc., have drawn much more attention because of their unusual electronic properties and ability to improve catalytic properties [9].…”

-Thanks to its planar structure, graphene is characterized by unique properties, such as excellent chemical inactivity, high electrical and thermal conductivity, high optical transparency, extraordinary flexibility and high mechanical resistance, which make it suitable in a very wide range of applications. This paper details the state of the art in graphene coating applied to aluminum open-cells foams for the improvement of their mechanical and thermal behavior. Metallic foams are highly porous materials with extremely high convective heat transfer coefficients, thanks to their complex structure of three-dimensional open-cells. Graphene nanoplatelets have been used to improve thermal conductivity of aluminum foams, to make them better suitable during heat transfer in transient state. Also, an improvement of mechanical resistance has been observed. Before electrodeposition, all the samples have been subjected to sandblasting process, to eliminate the oxide layer on the surface, enabling a better adhesion of the coating. Different nanoparticles of graphene have been used. The experimental findings revealed a higher thermal conductivity for aluminum open cells foams electroplated with graphene. Considered the relatively low process costs and the improvements obtainable, these materials are very promising in many technological fields. The topics covered include surface modification, electrochemical plating, thermo-graphic analysis.

Glass fiber-reinforced aluminum foam and its modified forms, using 1 and 3 wt.% of Cu, were produced by powder sintering process, using spherical carbamide particles as space holders. The foams with 40 and 60 vol.% porosity fractions were successfully produced after water leaching and sintering procedures. Compression test was performed on foam samples to compare both, the compressive properties and energy absorption behavior of them. The composite foam samples with Cu modification have shown a higher compressive strength than the parent material foam. The average plateau stress and energy absorption capacity of foams produced in this study, achieved via utilizing 3 wt.% Cu, were 7.06 MPa and 3.51 MJ/m 3 , respectively.

Uniaxial compression experiments on open-cell copper foams are conducted at strain rates of 10 À2 s À1 , 10 À3 s À1 , and 10 À4 s À1 to obtain the true stress-strain curves. The effects of the strain rate, cell size, and porosity on the mechanical properties is studied. The deformation mechanism of the open-cell copper foams is investigated by experimental research and finite element analysis. The results showed that the compression strength, Young's modulus and yield strength increase with increasing strain rate and decreasing porosity and cell size. A lower strain rate results in higher strain sensitivity. Strainhardening behavior occurred in the process of high-strain-rate loading. The experimental and simulation results indicate that the failure mechanism of the open-cell copper foam is the layer-by-layer collapse failure mechanism and that stress concentrations form easily at the weak pore struts. The simulation results are consistent with the experimental data at the first and second stages. However, the value of true stress predicted by the simulation at the third stage is slightly higher than that of the experiments.
