Influence of Corrosion Scales on Steel Corrosion Behavior in CO2/H2S Environments
Abstract
This review overviews recent advancements in studying corrosion scales formed on CS and low alloy steel surfaces in CO2/H2S environments.It discusses the chemical reactions, kinetics, mechanisms, classifications, influential factors, formation rates, types, and inhibitive properties of corrosion product scales that develop on steel surfaces.It thoroughly investigates phase transitions, the nature and composition of corrosion product scales, and their impact on the corrosion process by influencing the kinetics of anodic reaction (metal dissolution) and/or cathodic reaction (oxygen reduction/HER), which protect the corroding steel surfaces.Lastly, it emphasizes crucial research areas, knowledge gaps, future perspectives, and approaches for scale mitigation.
