“…Finally, SAMs can also work as effective protection layers for Ag films. [ 190–194 ] Several studies have shown the protection property of thiol compounds on Ag surfaces. Due to their ability to form densely packed and complete films on metallic supports, SAMs derived from thiols are useful in blocking electron transfer or in inhibiting the transport of corrosive species.…”

Transparent conductors are essential elements in an array of optoelectronic devices. The most commonly used transparent conductor – indium tin oxide (ITO) suffers from issues including poor mechanical flexibility, rising cost, and the need for annealing to achieve high conductivity. Consequently, there has been intensive research effort in developing ITO‐free transparent conductors over the recent years. This article gives a comprehensive review on the development of an important ITO‐free transparent conductor, that is based on thin metal films. It starts with the background knowledge of material selection for thin‐metal‐film‐based transparent conductors and then surveys various techniques to fabricate high‐quality thin metal films. Then, it introduces the spectroscopic ellipsometry method for characterizing thin metal films with high accuracy, and discusses the optical design procedure for optimizing transmittance through thin‐metal‐film‐based conductors. The review also summarizes diverse applications of thin‐metal‐film‐based transparent conductors, ranging from solar cells and organic light emitting diodes, to optical spectrum filters, low‐emissivity windows, and transparent electromagnetic interference coatings.

“…At lower frequency the loop is attributed to the relaxation process of the adsorbed intermediates by controlling the anodic process [17]. The impedance spectra of BFC were deviated from perfect semicircle due to frequency dispersion effect as a result of roughness and in-homogeneity on the metal surface [18,19]. Furthermore, the diameter of the capacitive loop in presence of BFC is higher than in HCl and its magnitude is a function of the inhibitor concentration.…”

The corrosion inhibition effect of N-(4-((4-Benzhydryl piperazin-1-yl) methyl Carbamoyl) Phenyl) Furan-2-Carboxamide (BFC) on brass in 1M HCl has been investigated using weight loss method, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV). The result reveals that BFC acts as a mixed type corrosion inhibitor with more pronounced effect on anodic domain and the inhibition efficiency of BFC increases with increase in temperature ranges from 30 ∘ C to 60 ∘ C. AC impedance implies that R ct value of BFC increases with increase in concentration. CV indicates that the addition of inhibitor controls the oxidation of the copper on the brass metal. The structural confirmation of BFC was carried out by the spectral studies like FT-IR, 1 H NMR, 13 C NMR, and the molecular weight was confirmed by LC-MS. Surface characterization of brass with BFC was analysed using scanning electron microscope (SEM). Quantum chemical parameter was used to calculate the electronic properties of BFC in order to confirm the correlation between the inhibitor effect and molecular structure of BFC. BFC has more negative charge on nitrogen and oxygen atom, which facilitates the adsorption of BFC on the surface of brass.

“…Gold and silver were among the first metals used by ancient societies; both are transition metals with shiny appearances [35]. Gold and silver have excellent corrosion resistance, they are soft, ductile, and malleable metals with superb reflectivity and high electrical and thermal conductivity [36,37]. Electrum, a gold-silver alloy that usually contains 60 wt.%-80 wt.% Au and 20 wt.%-40 wt.% Ag [38], was initially used during the first millennium BCE.…”

“…Applying gold, silver, and electrum coatings over objects made of aluminum alloys can efficiently shield the parts against corrosion in many severe environments, for instance, protection against pitting corrosion of Al in a surrounding of NaCl solutions [36]. Silver deposition is often used to coat aluminum micro-mirrors when high reflectivity is needed in the visible light, near infrared light, and radio frequency wavelengths [41].…”

Additive manufacturing (AM) revolutionary technologies open new opportunities and challenges. They allow low-cost manufacturing of parts with complex geometries and short time-to-market of products that can be exclusively customized. Additive manufactured parts often need post-printing surface modification. This study aims to review novel environmental-friendly surface finishing process of 3D-printed AlSi10Mg parts by electroless deposition of gold, silver, and gold–silver alloy (e.g., electrum) and to propose a full process methodology suitable for effective metallization. This deposition technique is simple and low cost method, allowing the metallization of both conductive and insulating materials. The AlSi10Mg parts were produced by the additive manufacturing laser powder bed fusion (AM-LPBF) process. Gold, silver, and their alloys were chosen as coatings due to their esthetic appearance, good corrosion resistance, and excellent electrical and thermal conductivity. The metals were deposited on 3D-printed disk-shaped specimens at 80 and 90 °C using a dedicated surface activation method where special functionalization of the printed AlSi10Mg was performed to assure a uniform catalytic surface yielding a good adhesion of the deposited metal to the substrate. Various methods were used to examine the coating quality, including light microscopy, optical profilometry, XRD, X-ray fluorescence, SEM–energy-dispersive spectroscopy (EDS), focused ion beam (FIB)-SEM, and XPS analyses. The results indicate that the developed coatings yield satisfactory quality, and the suggested surface finishing process can be used for many AM products and applications.
