“…10a, Table 5). The peak at lower bending energy (706.7 eV) is attributed to metallic iron as previously reported [52], while that at 710.4 eV assigned to Fe 3+ as mentioned in [53], is associated to ferric oxide/hydroxide species such as Fe 2 O 3 , Fe 3 O 4 and FeOOH [54,55]. The last peak at 714.1 eV was partly ascribed to the satellite of Fe(III) [56] and partly related to the presence of a small concentration of FeCl 3 on the steel surface due to the testing environment [57,58].…”

The effect of the increase in crystalline defects in the structure generated by high-pressure torsion (HPT) on the corrosion behavior of metallic materials is not well understood. This report evaluates the influence of HPT on the corrosion behavior of a solution treated Al-3wt% Mg-0.2wt% Sc alloy in a 3.5 wt./v.% NaCl solution. The electrochemical behavior of the alloy was evaluated using cyclic polarization, electrochemical impedance spectroscopy (EIS), Mott Schottky, X-ray photoelectron spectroscopy, and chronoamperometry testing. The passive current density decreased after HPT processing, indicating a more protective oxide layer was formed on the surface of the HPT-processed alloy. Mott Schottky analysis confirmed the higher protection efficiency of the passive layer on the HPT-processed alloy. The film formed in the solution-treated alloy was a p-type and an n-type semiconductor while the alloy processed by HPT exhibited only an n-type semiconductor behavior. EIS showed that corrosion resistance in a saline medium increased with HPT processing.

“…Many authors have investigated corrosion resistance of Al-Mg-Si (6xxx series) [20][21][22][23][24][25][26][27][28] and Al-Si alloys [29][30][31][32][33][34][35]. Regarding Al-Mg-Si alloys, pitting and intergranular corrosions (IGC) have been reported as localized corrosion features [23,27].…”

Corrosion properties of two Al-Si alloys processed by Rheo-high pressure die cast (HPDC) method were examined using polarization and electrochemical impedance spectroscopy (EIS) techniques on as-cast and ground surfaces. The effects of the silicon content, transverse and longitudinal macrosegregation on the corrosion resistance of the alloys were determined. Microstructural studies revealed that samples from different positions contain different fractions of solid and liquid parts of the initial slurry. Electrochemical behavior of as-cast, ground surface, and bulk material was shown to be different due to the presence of a segregated skin layer and surface quality.
