“…In acidic solutions the main anodic reaction is the dissolution of aluminum in the form of Al 3+ aqueous complexes and their passage from the metal surface into the solution, while the main cathodic reaction is a reduction of hydrogen ions and evolution of hydrogen gas [17]. Therefore, the inhibitor can influence on either the anodic or the cathodic reaction, or both.…”

Background and Purpose: Recent research indicates that a weed like Indigobush (Amorpha fruticosa L.) gives great opportunities for its commercialization through a rich spectrum of its beneficial biological features with possible use in the forestry and biotechnology field. Therefore, in this study we wanted to explore some of potential application of Indigobush extract, as a source of biologically active compounds, for animal cell culturing as well as green corrosion inhibitors. Materials and Methods: The effect of ethanol extract of Indigobush seeds was studied on human tumor cell lines (HeLa and MCF-7) and cell viability was determined by WST-1 method after 72 hours of treatment with 6 different extract concentrations (0.5-10 mg•mL-1). The inhibition effect of Indigobush seeds extract on the corrosion of aluminum in 0.5 M hydrochloric acid solution was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. Results: Results showed that the addition of Indigobush extract had a stimulatory effect on MCF-7 cells growth at the concentrations >1 mg•mL-1 while the same effect on HeLa cells was observed only

“…anodizing at potentiodynamic or potentiostatic conditions. Among several parameters, solution pH has one of the largest influences on the oxide film stability [14][15][16][17][18]. Below pH 4, and especially above pH 8, the oxide film is less protective due to the active dissolution of the base metal and an increased destabilization of the film [19].…”

“…It has been reported that citrate ions from the bulk solution have a strong tendency to adsorb onto the hydrated alumina surface forming surface complexes. [17,[20][21][22]. Also, the presence of some halogen-ions, especially chloride ions, may significantly destabilize the oxide film on Al due to the strong dissolution of oxide film caused by the localized attack [23,24].…”

The growth kinetics and properties of potentiodynamically formed thin oxide films on Al were investigated in 0.05 M citric acid solutions of different pH (5, 6 and 7) by means of potentiodynamic polarization and a.c. electrochemical impedance spectroscopy (EIS) measurements. Al showed passive behaviour within the pH range that was examined. The potentiodynamic growth of the oxide film on Al takes place due to ionic conductivity under the influence of the high electric field. Characteristic kinetic oxide film growth parameters such as the high-field growth exponential law constants (A and B), ionic conductivity through the oxide film, field strength and half barrier width have been calculated. Impedance measurements were used to determine the parameters related to the characteristic sizes and properties of oxide film. The capacitive response of the impedance spectrum was related to the thickness and dielectric properties of the barrier oxide film. The oxide film resistance values were very high, indicating that the oxide films formed under potentiodynamic conditions are highly uniform in thickness and very resistant. The anodic behaviour of Al in the citric solutions under potentiodynamic conditions were characterized by the rapid growth of the oxide film which diminished the influence of relaxation processes on the growth kinetics and structural characteristics of the aluminium/anodic oxide film/electrolyte system.

“…These two characteristics are related to physicochemical features of the amorphous alloys and to their electrochemical corrosion resistance in particular. Amorphous Al-based alloys show higher chemical resistance in aggressive media than crystalline ones [6][7][8]. This is related to the absence of inhomogeneities on the surface of the alloys, since inhomogeneities promote the localization of surface energy and decrease the chemical resistance [6].…”

The influence of the formation of intermetallic compounds on the electrochemical properties of an Al 87 Y 5 Ni 8 amorphous metallic alloy (AMA) was investigated by means of differential scanning calorimetry (DSC), X-ray diffraction (XRD) and high-resolution electron microscopy (HREM). It is shown that the crystallization process taking place upon annealing can be subdivided into three stages corresponding to DSC maxima at 505, 602 and 632 K, respectively. The first and the second stage of crystallization were attributed to the formation of an fcc-Al(Y) solid solution in the amorphous matrix. During the third stage of crystallization precipitation of the fcc-Al(Y) solid solution and of the ternary compound Al 19 Y 3 Ni 5 with orthorhombic Al 19 Gd 3 Ni 5type structure was observed. An increase of the size of the precipitated phases reduces the corrosion rate coefficient b of the AMA.
