dc.description.abstractMaterial loss due to corrosion can weaken the structural integrity of systems and potentially lead to failure if timely action is not taken. Such deterioration adversely affects the dynamic behavior of metals. This study deals with the post-corrosion changes in the dynamic behavior of AISI 4140, AISI 4340 and AISI 5140 metals after exposure to 3.5 w /% NaCl for 1, 7, 15 and 30 days. Electrochemical impedance spectroscopy (EIS) and dynamic electrochemical impedance spectroscopy (dynamic EIS) were used to elucidate the corrosion mechanisms. Modal analysis and finite element method (FEM) were used to characterize dynamic behavior changes. In addition, scanning electron microscopy (SEM-EDS) was used to analyze changes in the surface morphology after corrosion. The results showed a decrease in the corrosion resistance of AISI 4140, AISI 4340 and AISI 5140 metals over time, although there was an improvement after 30 days. The electrochemical test results indicated that the metal with the highest corrosion resistance in the 3.5 w /% NaCl environment was AISI 4340, while AISI 5140 showed the lowest resistance. In particular, natural frequency values showed a decreasing trend with increasing corrosion exposure time, accompanied by discernible changes in mode shapes.en_US
