“…The use of EO water as a sanitizer in food processing plants has been suggested because of its high antimicrobial activity, low cost and ease of production and use, among other advantages. Although EO water has demonstrated a strong bactericidal activity, the possibility of corrosion of equipment because of its low pH and residual chlorine content is a matter of concern because acids and aqueous forms of chlorine are known to be corrosive (Daufin et al 1988a;Bohner and Bradley 1991;McCafferty 2003;Abd El Meguid and Abd El Latif 2004). Most metals corrode when they come in contact with water, acids, bases, salts, some chemicals and gaseous compounds like acid vapors, sulfur-containing gases and ammonia gas.…”

ASTM A‐36 medium carbon steel, 110 copper, 3003‐H14 aluminum, polyvinylchloride (PVC) type 1 and 304 stainless steel coupons were immersed in electrolyzed (EO) water, chlorine water, modified EO water and deionized water for a period of 8 days, and the properties of these types of water, weights and surface roughness of the coupons were monitored. EO water significantly increased (P < 0.05) the surface roughness of carbon steel, aluminum and copper with time; however, chlorine water, modified EO water and deionized water produced minimal changes on these materials. Regardless of the treatment water used, the surface roughness of stainless steel and PVC essentially remained the same. Carbon steel, copper, aluminum and stainless steel had a fair, good, good and outstanding corrosion resistance in EO water, respectively. Chlorine and modified EO water had a much less corrosive effect than EO water on all the materials tested.

“…The addition of 0.5 m HCO 3 -to a 4 % NaCl solution completely inhibits the crevice corrosion of 254 SMO SS at 70 ° C (Abd El Meguid & Abd El Latif, 2004). E p of 316L SS increases with increasing the concentration of HCO 3 -in a 0.5 m NaCl solution (Park, Pyun, Lee, & Kim, 1999).…”

“…Bromide ion is also detrimental. However, it is generally less aggressive than chloride (Abd El Meguid & Abd El Latif, 2004;Rebak, Koon, Cotner, & Crook, 1999). As long as molybdenum contents of the alloys increase, bromide ion becomes more detrimental than chloride (Kaneko & Isaacs, 2002).…”

“…Sulfate cannot be reduced within a low pH environment. Supporting electrolyte effect, including competitive adsorption of chloride and sulfate on the SS surface is usually postulated (Abd El Meguid & Abd El Latif, 2004;Brossia & Kelly, 1998;Ü rgen & Ç akir, 1991;Yashiro et al, 1997). Thus, the critical chloride concentration needed for the fi lm breakdown is more diffi cult to reach.…”

The application of stainless steels and chromium containing nickel-based alloys is limited by their susceptibility to localized corrosion in the forms of pitting and crevice corrosion or environmentally assisted cracking. Inhibitors may be normally found in service environments or added on purpose to mitigate or avoid the effects of aggressive agents such as chloride ions. The present study critically reviews the present knowledge on inhibition of chloride-induced pitting and crevice corrosion. Pioneering studies and recent fi ndings are analyzed in light of the present theories for describing the localized corrosion processes. This review particularly focuses on the inhibition of crevice corrosion of alloy 22, which has been thoroughly studied in the past decade.

Crevice Corrosion of Stainless Steels 904L, 2205, and 2507 in High-Temperature Sulfuric Acid Solution Containing Chlorides: Influence of Metal Cations

Crevice corrosion of stainless steels 904L, 2205 and 2507 in high-temperature sulfuric acid solution containing chlorides: Influence of metal cations (2018). Crevice corrosion of stainless steels 904L, 2205 and 2507 in high-temperature sulfuric acid solution containing chlorides: Influence of metal cations. Corrosion, 74(2), 225-240. https://doi. AbstractCrevice corrosion influences the integrity of materials in many industrial sectors, such as hydrometallurgy. The conditions in hydrometallurgical processes are severe, with high concentrations of sulfuric acid leachant as well as high chloride impurity, oxygen and metal cation contents. In this study, crevice corrosion behaviour of highly-alloyed austenitic and duplex stainless steels is investigated in aerated high-temperature sulfuric acid solution with 1 g/l chlorides in the presence of three types of metal cations: Fe 3+ , Cu 2+ , and Fe 2+ . The experimental work contained determination of the oxidizing capacity of the solutions, immersion crevice corrosion tests followed by characterization of the corrosion attack, and potentiodynamic polarization measurements. The results showed that the alloy with the highest PREN-value, 2507, was not susceptible to crevice corrosion under the test conditions. In the case of alloys 904L and 2205 of relatively equal PRENvalues, the extent and nature of crevice corrosion attack was different and dependent on the ratio 2 of activities of chlorides to sulfates and the type of metal cations. The results are presented and discussed in the light of IR drop mechanism.
