Relationship between Dissolved Oxygen and Corrosion Characterization of X80 Steel in Acidic Soil Simulated Solution
The relationship between dissolved oxygen (DO) and corrosion behavior of X80 steel in acidic soil simulated solution was studied by potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS), scanning Kelvin probe technique (SKP) and X-ray diffraction (XRD). Results showed that the presence of DO accelerated the cathodic process of corrosion for X80 steel in the acidic so...
متن کاملCorrosion Fatigue of 17-4pH Stainless Steel in a Simulated Sea Water Solution
Since martensitic precipitation hardened 17-4pH stainless steel has been widely used in corrosive environments, evaluation of its corrosion fatigue behavior is important. In this research, after microstructural studies, mechanical, corrosion, fatigue and corrosion fatigue tests were performed on 17-4pH specimens. Fatigue and corrosion fatigue tests were carried out at the stress ratio of -1 an...
متن کاملInfluence of Sulfate-Reducing Bacteria on the Corrosion Behavior of High Strength Steel EQ70 under Cathodic Polarization
Certain species of sulfate-reducing bacteria (SRB) use cathodes as electron donors for metabolism, and this electron transfer process may influence the proper protection potential choice for structures. The interaction between SRB and polarized electrodes had been the focus of numerous investigations. In this paper, the impact of cathodic protection (CP) on Desulfovibrio caledoniens metabolic a...
متن کاملCharacteristics of Corrosion Scales on Pipeline Steel in CO2- Saturated NaCl Brine Solution
The present study is aimed to conduct the experiments in various corrosive environments at various temperatures and constant partial pressures of carbon dioxide (CO2) under dynamic condition to understand the basic mechanism and corrosion resistance of carbon steel. Usually, API grade steels are used in the pipeline for carrying the crude oil and gas. Corrosion problems constitute the major ope...
