Abstract
In the present study, corrosion tests of magnesium matrix composite materials containing 5-25% by volume TiNi produced by uniaxial hot pressing technique were carried out with potentiodynamic polarization (PDS) tests in 3.5% NaCl solution. Corrosion potential (E<inf>cor</inf>) and corrosion current density (ί<inf>corr</inf>) values of composite specimens were specified by the use of the Tafel extrapolation method. Metallographic examinations have shown that the observed changes in microstructure are consistent with electrochemical values. In potentiodynamic polarization analysis, corrosion potential values alongside corrosion current density values, depending on the reinforcement content, were significantly found to increase. In post-corrosion morphological investigations, filiform corrosion was observed besides pitting corrosion on the sample surfaces. © 2025 Elsevier B.V., All rights reserved.
