Investigating the Corrosion Behaviour and Electrochemical Properties of Intermetallic Matrix Composites

In the realm of advanced materials, intermetallic matrix composites (IMC) have garnered significant attention due to their potential for high-temperature applications and superior mechanical properties. This research delves into the corrosion behaviour and electrochemical characteristics of selected IMCs to elucidate their performance in aggressive environments. Employing potentiodynamic polarization tests and electrochemical impedance spectroscopy (EIS) , the study provides a comprehensive analysis of the corrosion kinetics and mechanisms inherent to these materials. The results indicate that the microstructural features, including the distribution of secondary phases and the nature of the matrix, play a pivotal role in determining the corrosion resistance. Furthermore, the presence of certain alloying elements was found to impart passivation capabilities, thereby enhancing the overall corrosion resistance. The EIS data revealed distinct time constants, suggesting multiple electrochemical processes at the interface. This study not only advances our understanding of the corrosion behaviour of IMCs but also underscores the importance of microstructural engineering in tailoring their electrochemical properties. The insights garnered hold profound implications for the design and application of IMCs in industries where corrosion resistance is paramount
