摘要：
This paper studies the electrochemical behavior of 42CrMo4 QT steel, which is used as structural steel in various industries, such as shipbuilding. The quenching and tempering treatment produces a bainitic microstructure composed of ferrite and acicular cementite. In addition, alloying elements may segregate during the steelmaking process. Detailed characterization of the steel microstructure was performed using a scanning electron microscope and EDS spectroscopy so as to evaluate the morphology and chemical composition of inclusions present in the steel microstructure. The initiation of pitting corrosion on sites with the presence of inclusions was studied using a localized approach by studying the corrosion morphologies after immersion in aggressive electrolyte. The effect of different types of inclusions was discussed by considering galvanic coupling with the steel matrix and with the presence of crevices at the inclusion/matrix interface.
