<p>In this study, the relationship between the microstructure and the electrochemical behavior and corrosion resistance of AISI 316 stainless steel reinforced with 2, 4, 6, and 8% vol of silicon carbide (SiC) particles, developed using the powder metallurgy technique, was evaluated. It was found that ceramic particles favor the results of the sintering process, once the porosity decreases and the densification of the material increases; however, a 2% vol. SiC content is not sufficient for a significant decrease in porosity, and above 6% vol. SiC increased porosity due to a greater number of interfaces. Diffraction patterns revealed the coexistence of the γ-austenite and SiC phases to composite formation. The results from the electrochemical impedance (EIS) and potentiodynamic polarization (PP) tests showed a higher capacitive arc for SS-SiC 4% sample with a real impedance of 6.10E + 02 Ohm.cm², higher polarization resistance with a value of 5.80E + 03&#xa0;V, and corrosion potential (− 0.492&#xa0;V), indicating an increase in the electrochemical and corrosion resistance properties with respect to AISI 316 steel unreinforced.</p> Graphical abstract <p></p>
