Modeling of Atmospheric Corrosion Behavior of Weathering Steel in Sulfur Dioxide-Polluted Atmospheres

RETRACTED: Mechanical properties and corrosion resistance of low-alloy steels in atmospheric conditions containing chloride

“…The lighting source was an UVB-313 tube. The dry/wet ratio was 2:1, which was more severe than conditions in a previous study (drying period for 18 h and wetting period for 6 h) [13]. This was done to determine whether the differences between WS and CS would be more significant than those under the dry/wet ratio of 3:1 if the time of wetness increased during the 24 h cycle.…”

“…For this reason, it is necessary to develop different types of WS that are suitable locally. Therefore, the high phosphorus weathering steel, the so-called Acr-Ten A, has been demonstrated to have a better corrosion resistance than carbon steels (CS) in various atmospheres of Taiwan island [12,13].…”

“…(Table 2) shows that the sulphate content in UNICAL is more than those in the other stations and may be responsible for the higher corrosion rate in UNICAL. Sulphate ions in thin electrolyte layer interferes with the formation of an intermediate species (Fe(OH) ads ) in the iron corrosion reaction according to the process (Wang et al, 1996) This interference leads to acceleration in corrosion rates. However, the corrosion rates for all the stations fall within the excellent relative corrosion resistance range (Jones, 1996) and thus the atmosphere can be considered not to be corrosive to mild steel.…”

Interface analysis of pure Sn, pure Ag and SnAg binary alloys in H2SO4

“…Furthermore, impedance diagrams for each alloy clearly portray a decrease in the impedance modulus |Z| value with increase of acid concentration, indicating a decrease in the stability of the alloy. The dispersive behavior of the obtained impedance spectra (IS) characterizing a nonhomogeneous oxide layer with porous nature can be described using instead of pure capacitance a constant phase element (CPE) which has an impedance defined as [23] …”

“…the impedance is best described by an ideal capacitor, so that Y o = C. For the case α = 0.5, an impedance relation, known as the Warburg impedance, is applicable; this impedance is associated with concentration-and diffusion-related processes. [23,24] For alloy I the EIS data were best fitted to an equivalent circuit of the Voight model shown in Fig. 7(a).…”
