“…A researcher group, led by Gupta et al [26] demonstrated that the SEM technique can be used to characterize the grain nucleation and size as a function of the processing parameters, and discovered that the key processing parameters were electrolyte concentration, current, voltage, and deposition time. Several researchers [30,42,43] have demonstrated that electrodeposited films have a nodular grain nucleation and growth, until a smooth surface is achieved. Figure 4 shows different stages of this process where it can be seen that at 0.5 h, the grain morphology corresponds to nodular grain nucleation and growth, as reported by other authors [30,42,43].…”

This research aimed to obtain a C-based coating electrochemically applied on an AA6063 alloy. Two electrochemical cells were designed and manufactured to obtain the C-based coating film on flat and cylindrical samples. Structural and microstructural characterizations were performed along with fatigue and corrosion performance testing. The structural and microstructural characterization revealed that the C-based coating deposited on AA6063 corresponded to carbon nanofibers and/or polycrystalline graphite. The performance testing showed an increase in fatigue life along with a decrease in corrosion resistance. The fracture surfaces of the fatigued samples were inspected by Scanning Electron Microscopy and 3D optical microscopy to correlate them with fatigue life estimation. The aforementioned process is a step towards the future development of a complete coating system that will overcome corrosion susceptibility. The carbon film obtained by this electrochemical route has not previously been reported elsewhere.

The excellent properties of titanium and its alloys make them a perfect choice for many applications. In this paper, the effects of thermal oxidation condition on the surface morphology and surface roughness have been studied. The results showed that the average roughness at temperatures 450 and 600uC did not change significantly. Despite the constant average roughness, skewness and kurtosis parameters have been changed considerably during the thermal oxidation. The results suggest that the valleys are preferred sites for nucleation and growth of oxides. This mechanism changes the surface morphology from a scratched surface to a bumpy one.

“…However, their applications have been limited due to the need for complicated and costly equipment, and rigorous preparation conditions, such as high substrate temperatures and high vacuum environments. In this context, electrochemical deposition, due to its flexibility in operating parameters, may be conducted at room temperature, which favors industrial applications, providing an alternative to traditional methods [14][15][16][17][18][19].Another advantage of the electrochemical technique is the possibility of directly synthesizing the sensing layer on the substrate. The sensors that are fabricated using direct synthesis are more sensitive than those with a sensing layer deposited via the strong adhesion of nanoparticles to the substrate [20].In this study, we designed gas sensor chips that are suitable for the electrochemical deposition of a gas-sensitive silicon-carbon film, doped with copper oxide, from an organic electrolyte.…”

Fabrication of Gas-Sensor Chips Based on Silicon–Carbon Films Obtained by Electrochemical Deposition

In this study, we designed two types of gas-sensor chips with silicon–carbon film, doped with CuO, as the sensitive layer. The first type of gas-sensor chip consists of an Al2O3 substrate with a conductive chromium sublayer of ~10 nm thickness and 200 Ω/□ surface resistance, deposited by magnetron sputtering. The second type was fabricated via the electrochemical deposition of a silicon–carbon film onto a dielectric substrate with copper electrodes formed by photoelectrochemical etching. The gas sensors are sensitive to the presence of CO and CH4 impurities in the air at operating temperatures above 150 °C, and demonstrated p- (type-1) and n-type (type-2) conductivity. The type-1 gas sensor showed fast response and recovery time but low sensitivity, while the type-2 sensor was characterized by high sensitivity but longer response and recovery time. The silicon–carbon films were characterized by the presence of the hexagonal 6H SiC polytype with the impurities of the rhombohedral 15 R SiC phase. XRD analysis revealed the presence of a CuO phase.
