[ 1 ] - An Electrochemical Measurement for Evaluating the Cathodic Disbondment of Buried Pipeline Coatings under Cathodic Protection

Steel pipelines are susceptible to corrosion by the action of corrosive substance in the environment and one of the most common failure modes in buried pipeline coatingis cathodic disbondment. Consequently, Electrochemical Impedance Spectroscopy (EIS) was used to assess the effect of three important parameters, the thickness of coating, the artificial defect ...

[ 2 ] - Corrosion Inhibition of Carbon Steel in SULFIRAN® Process

In this investigation, attempts were directed to study the inhibitive effects of nitrite and phosphate base inhibitors for the carbon steel alloy samples, which are used in an acid gas treatment process (The SULFIRAN® solution), in Fe-EDTA solution. Electrochemical techniques, i.e. polarization curves and electrochemical impedance spectroscopy (EIS), were used to evaluate the inhibition efficie...

[ 3 ] - Stress Corrosion Cracking Detection of Sensitized Stainless Steel 304 in Chloride Media by Using Electrochemical Impedance Spectroscopy (EIS)

Electrochemical impedance spectroscopy (EIS) was used to detect stress corrosion cracking (SCC) in stainless steel 304 alloy exposed to an aqueous environment at 120 °C. Stainless steel 304 alloy as u-bend was tested in the solution that contains 40 weight percent of magnesium chloride. U-bended samples were prepared according to ASTM G30. EIS measurements were always performed simultaneously o...

[ 4 ] - بررسی رفتار الکتروشیمیایی و خوردگی فولاد زنگ نزن 316L درفرآیند سولفیران

در این مقاله رفتار خوردگی فولاد زنگ‌نزن 316L درمحلول فرآیند سولفیران به طریق آزمایشگاهی و پایلوتی مورد ارزیابی قرار گرفت. از روش‌های الکتروشیمیایی شامل منحنی‌های تافل، منحنی‌های پلاریزاسیون چرخه‌ای و اسپکتروسکوپی امپدانس (EIS) در بررسی‌های آزمایشگاهی استفاده شد. آزمایش‌ها در محدوده دمایی C° 35-45 انجام شد. بررسی‌های آزمایشگاهی نشان داد نرخ خورگی آلیاژ فولادهای زنگ‌نزن SS316L کمتر از 1mpy در محی...
