Fecha de publicación: | 2021 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Metals 11 (3): 391 (2021) | Resumen: | The corrosion behavior of AZ31B Mg alloy exposed to Ringer's, phosphate-buffered saline (PBS), Hank's, and simulated body fluid (SBF) solutions for 4 days was investigated using electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, weight loss, and surface characterization. Changes in corrosion rates with immersion time determined by weight loss measurements were compared with EIS data to determine the possibility of obtaining quantitative electrochemical information. In addition, changes in the protective properties of the corrosion product layer calculated from the EIS parameters were evaluated as a function of their surface chemical composition as determined by X-ray photoelectron spectroscopy (XPS) and visual observations of the corroded specimen's surface. Apparent Stern-Geary coefficients for the AZ31B Mg alloy in each test solution were calculated using the relationship between i(corr) from weight loss measurements and the EIS data (both R-p and R-t). This provided experimental reference B ' values that may be used as a useful tool in independent investigations to improve the accuracy of corrosion rates of AZ31B Mg alloy in simulated body solutions. | Versión del editor: | https://doi.org/10.3390/met11030391 | URI: | http://hdl.handle.net/10261/264091 | DOI: | 10.3390/met11030391 | Identificadores: | doi: 10.3390/met11030391 issn: 2075-4701 |
