“…The anodizing voltage is one of the most important parts of the anodizing of aluminum because the oxide layer nucleation growth develops depending on the barrier layer [28]. The porous surface morphology is related to the alloy formation, applied current, electrolyte and time [7,27,29,30].…”

Coating of the metal surface for different fields such as corrosion resistance, hydrophobic surface, and conductivity properties enhance the material quality for different application. Furthermore, controlling the morphological structures and the size of the coating materials is one of the most important factors for designing their functionality. The new approaches to the effect of surface properties at the atomic level on bacterial adhesion offer new perspectives on this subject. In this study, the effect of the different current densities on the morphological microstructural features, micro hardness properties, and bacterial attachment behavior of the protective aluminum oxide layer was investigated by using different analytical and instrumental methods. The Staphylococcus aureus was used as a model bacteria for attachment tests. The result presented in the current study exhibited that the crystal morphology, hardness, and bacterial adhesion features have changed depending on the applied current density. The higher current density increases the surface roughness, hardness, and the size of the surface morphology and develops the bacterial attachment on the surface.

“…The results in figure 10 show that, in the bode plot of the coated sample, there are two-time constants in the low frequency region and the medium frequency region, which can be attributed to the presence of the silver coating. The time constant of medium frequency is attributed to the silver chloride film formed during corrosion [45,46]. The results show that when the average current density is 0.6 A cm −2 , the silver coating is smooth and dense, and has the best corrosion resistance.…”

Pulse electroplating technology has the characteristics of fine grain and good corrosion resistance. In order to ensure the good application of electroplated silver cone cavity in solar radiation detector. The effects of three process parameters, including average current density (0.4-1 A/dm2), pulse on-time (0.2-1.8 ms) and pulse off-time (0.8-4.8 ms), on the deposition rate, appearance and corrosion resistance of silver coating were studied by control variates. The surface morphology and composition of silver coatings were studied by scanning electron microscope (SEM), laser confocal microscopy and energy dispersive X-ray spectrometer (EDX). The corrosion resistance of silver coating in 3.5 wt.% NaCl solution was studied by polarisation curves and electrochemical impedance spectroscopy. The results show that pulse electroplating takes advantage of the dynamic change of current to influence the size of deposited particles and the degree of densification of the coating by precisely adjusting the pulse plating parameters, and ultimately obtains the coating with excellent morphology. The optimal parameters are: average current density 0.6 A/dm2, pulse on-time 1.2 ms, pulse off-time 1.8 ms. The silver coating prepared under process conditions has excellent corrosion resistance (7059 Ω/cm2). The surface crystal grain is dense, without obvious defects.

“…Atomic force microscopy (AFM) was used by the researchers to study and observe the evolution of surface morphology and surface parameters in diverse fields, especially corrosion science. [37][38][39][40] The AFM images (scan range 90 mm × 90 mm) of pure Al and its alloys 7S10 and 7003H are shown in Figure 7 before and after the immersion test. The images clearly show that the surface roughness was increased in the case of alloy 7003H.…”

Aluminum and aluminum alloys are light materials with some of the preferences such as lightweight, high specific strength, good elasticity, and good workability that play an important role in today's modern and industrial world. The economic loss and environmental and safety problems are also the most concerning aspects of these materials. As a result, numerous studies are performed by the researchers to improve the overall environment throughout the materials world. That is why, in this study, the surface morphology and corrosion behavior of pure aluminum and its alloys, such as 7S10 and 7003H, were investigated in aqueous sulfuric acid medium through immersion process at different temperatures. Open‐circuit potential and potentiodynamic polarization techniques were used to evaluate the resistance to corrosion of pure aluminum and its alloys 7S10 and 7003H. The current density increased with increasing temperature in the case of the alloys, and pure aluminum showed the highest corrosion resistance properties. The surface roughness measurement was performed using atomic force microscope to find out the amount of roughness of the used materials before and after the immersion process. Surface roughness was higher on the alloys than in pure Al, which indicates that less corrosion was formed in pure Al than in the alloys. The surface morphology analysis was also carried out using scanning electron microscopic data. The results revealed that the alloy 7003H undergoes more corrosion than pure aluminum and 7S10 in sulfuric acid medium, which clearly indicates that pure aluminum has higher corrosion resistance than the alloys 7S10 and 7003H. The corrosion rate of the test materials decreased with increasing immersion time.
