Assessing Pretreatment Effect on the Protective Properties of Different Coating Systems Against Marine Corrosion

Towards the Determination of the Origin of Sulfur Compounds in Marine Zones by Means of the Chloride/Sulfate Ratio: Applications in Atmospheric Corrosion Studies

“…The characteristics of the steel samples, their preparation before and after the experiment, as well as the setup during the experiments is detailed in a previous work. 15 The weight loss (W L ) of the steel samples was determined by calculating the mass loss over the area for an specific period of time, in agreement with previous studies. 4,6 The W L for each exposure time was calculated from the average of three determinations.…”

“…Corrosion rate evaluation.-The University of Matanzas (23 • 2 9 N latitude and 81 • 30 34 W longitude, Matanzas city) identified as E1 and Playa Caleta hotel (23 • 7 54 N latitude and 81 • 18 36 W longitude, Varadero city) identified as E2 were the selected areas for field tests, located 1250 m and 250 m, respectively, from the north coast of Matanzas province. More characteristics related to climatology, pollution and corrosive aggressiveness of both stations, determined in previous investigations, 15,17 are listed in Table I. Both locations, are under marine influence and fulfil the general requirements for this kind of experiments.…”

“…Also, ASP was the retention method leading to the highest levels of SO 4 2− and Cl − ions and consequently, higher regression coefficients for the ions deposition and the corrosion rate were obtained. 15 Factors such as the nature of the surface (dry or wet, more or less rough), composition (e.g. the alkaline surface of the ASP collector favors sulfur compounds precipitation, which is not the case for the WC and DP collectors), form (cylindrical, flat) and disposition to outdoor conditions are responsible for the differences mentioned, as explained previously.…”

“…the alkaline surface of the ASP collector favors sulfur compounds precipitation, which is not the case for the WC and DP collectors), form (cylindrical, flat) and disposition to outdoor conditions are responsible for the differences mentioned, as explained previously. 15 Hence, the determination of atmospheric pollutants by using different collectors may lead to erroneous results and misinterpretations.…”

Ionic liquids improve the anticorrosion performance of Zn-rich coatings

“…3 Within the latter, the use of ionic liquids for metal protection is a subject of particular importance and practical signicance, since it may open up new opportunities in the eld of corrosion inhibition. [4][5][6][7] Since corrosion involves losses of millions dollars worldwide, 8 the pursuit of more efficient protective methods is desired. Among the existing alternatives, epoxy coatings have been widely used in combination with other protective additives (e.g.…”
