摘要：

The paper presented a number of issues regarding the evolution of the macro and microstructural degradation occurring in the superficial layer of a naval steel, grade F-36 subject to fatigue tests in corrosive environment. Studies have been carried out on the evolution of the electrode potential, the dislocation density and the micro and macrostructure modification. The analysis of these evolution processes highlights the fact that the process of degradation by corrosion fatigue is initiated by localised corrosion processes.
