“…For both temperatures applied, thick but nonuniform deposits were obtained (Figures 7c,d and 8). At a higher magnification, grains of different sizes similar to those obtained from AlCl3-BMIC ILs on mild steel published recently [27] can be observed. The energy-dispersive spectroscopy (EDS) analysis made from a larger portion of the same deposits (approximately 400 µm 2 ) reported 36.7 wt.…”

Al-Ti alloys were electrodeposited from equimolar chloroaluminate molten salts containing up to 0.1 M of titanium ions, which were added to the electrolyte by potentiostatic dissolution of metallic Ti. Titanium dissolution and titanium and aluminium deposition were investigated by linear sweep voltammetry and chronoamperometry at 200 and 300 °C. Working electrodes used were titanium and glassy carbon. The voltammograms on Ti obtained in the electrolyte without added Ti ions indicated titanium deposition and dissolution proceeding in three reversible steps: Ti4+ ⇄ Ti3+, Ti3+ ⇄ Ti2+ and Ti2+ ⇄ Ti. The voltammograms recorded with glassy carbon in the electrolyte containing added titanium ions did not always clearly register all of the three processes. However, peak currents, which were characteristics of Al, Ti and Al-Ti alloy deposition and dissolution, were evident in voltammograms on both working electrodes used. A constant potential electrodeposition regime was used to obtain deposits on the glassy carbon working electrode. The obtained deposits were characterized by SEM, energy-dispersive spectrometry and XRD. In the deposits on the glassy carbon electrode, the analysis identified an Al and AlTi3 alloy formed at 200 °C and an Al2Ti and Al3Ti alloy obtained at 300 °C.

“…Subsequently, ILs received increasing attention due to their extraordinary physicochemical properties including low melting point, low vapor pressure, high conductivity, and wide potential window. In recent decades in particular, ILs have been considered a promising, green medium for reactive metal electrodeposition, replacing high-temperature molten salts [4][5][6][7][8][9][10].…”

Ionic liquids are considered environmentally friendly media for various industrial applications. Basic data on physicochemical properties are significant for a new material, in terms of developing its potential applications. In this work, 1-ethyl-3-methylimidazolium fluoride ([EMIm]F) ionic liquid was synthesized via an anion metathesis process. Physical properties including the density, viscosity, electrical conductivity, and thermal stability of the product were measured. The results show that the density of [EMIm]F decreases linearly with temperature increases, while dynamic viscosity decreases rapidly below 320 K and the temperature dependence of electrical conductivity is in accordance with the VFT (Vogel-Fulcher-Tammann) equation. The temperature dependence of the density, conductivity, and viscosity of [EMIm]F can be expressed via the following equations: ρ = 1.516 − 1.22 × 10 −3 T, σ m = 4417.1exp[−953.17/(T − 166.65)] and η = 2.07 × 10 −7 exp(−5.39 × 10 4 /T), respectively. [EMIm]F exhibited no clear melting point. However, its glass transition point and decomposition temperature are −71.3 • C and 135 • C, respectively.

“…Though there are certain advantages on obtaining Al-Ti deposits from such substrates such as (i) simple pretreatment, (ii) noble character, (iii) electrochemical stability, it will be very more beneficial to deposit corrosion-resistant Al-Ti coatings on industrially used substrates, especially mild steel owing to their numerous applications in different industry segments. Xu et al [75] studied the electrodeposited Al-Ti alloy in a Lewis acidic [BMIm][Cl]-AlCl 3 -based IL with different Ti(IV) ion concentrations, investigated the co-deposition behavior detail under galvanostatic conditions with different applied current densities at a deposition temperature of 70 • C. Dense and adherent Al-Ti deposits were reported to be obtained on mild steel substrates with varying Ti content from 5.3 to 11.4 at.%. They also investigated the current density effects, influence of TiCl 4 concentration and studied its relation to the Al-Ti alloy composition and surface morphology of the obtained deposits.…”

Aluminum plays an essential role as an excellent coating material in diversified applications due to its better corrosion resistance and physicochemical properties. Employing such a material as a coating on different metallic substrates such as carbon steel would benefit many industries such as the automotive, aviation, shipbuilding, construction, electronics etc. Amongst the various available coating techniques, electrodeposition of aluminum (Al) Al alloys have gained significant attention in the last 10 years as a metallic protection coating for various commercial substrates and has become the industry’s choice owing to being lightweight, corrosion-resistant, and cost-effective. This paper shall provide a detailed review covering electrochemical deposition of Al and Al alloys using ionic liquids with various cations, anions, and additives, and reports on progress in development thus far. It shall also cover the challenges in the electrodepositing aluminum, its alloys on light weight metal substrates viz., magnesium (Mg), commercial substrates such as low carbon steel, spring steel, and their pretreatments. The factors that play an important role in electroplating on an industrial scale, along with future challenges, are discussed.
