Corrosion of AD31 (AA6063) Alloy in Chloride-Containing Solutions

Corrosion properties of nickel coatings obtained from aqueous and nonaqueous electrolytes

“…This element takes into account the surface roughness. The impedance of the CPE element is expressed by the formula: where Y 0 is the CPE constant; n (0 ≤ n ≤ 1) is the mathematical factor showing the deviation from the ideal capacitor in the impedance response; j is the imaginary unit; and w is an angular frequency, rad −1 .…”

“…Nickel coatings are quite stable in alkaline media but are easily dissolved in most acids, and many ions, for example, chloride or fluoride, cause rapid deterioration of the metal surface. For this reason, chloride‐containing media are widely used to study corrosion processes . Nickel coatings are also used under different conditions, and this requires study of the corrosion behavior of nickel coatings in the most prevalent aggressive environments …”

“…For this reason, chloride-containing media are widely used to study corrosion processes. 34,35 Nickel coatings are also used under different conditions, and this requires study of the corrosion behavior of nickel coatings in the most prevalent aggressive environments. 36,37 The aim of this work was to study the microstructure and corrosion resistance of nickel coatings deposited from aqueous and nonaqueous electrolytes in acidic, alkaline, and neutral chloride-containing media.…”

Corrosion of Al85Ni9Ce6 amorphous alloy in the first hours of immersion in 3.5‐wt% NaCl solution: The role of surface chemistry

“…Zhang et al attributed the inductive response to the generation of Al 3+ ion at anodic sites, as also suggested by other authors. The inductive behavior of Al alloys is associated with the presence of adsorbed species such as Al + ads and Al 3+ ads that would take place as the alloy dissolves. It is often related to poor corrosion protective ability and propensity to localized corrosion processes.…”

DÖKÜM Al-10Mg2Si İN-SİTÜ KOMPOZİTLERİN KOROZYON

“…It is generally accepted that the R1 and R2 values have a direct proportional to corrosion resistance. The higher R1 and R2 values indicate more difficult charge transfer between the sample and solution [24,25]. The R1 values of 473, 305 and 118 /cm 2 and the R2 values of 1623, 1014, 773 /cm 2 were calculated for the alloys taken from Section 1, Section 2 and Section 3, respectively.…”
