Application of Electrochemical Techniques in Stainless Steel 316L for a Prosthesis with Aloe-Vera extract Inhibitor

摘要

The study of the Aloe-Vera employed as the protection of the stainless steel 316 using different electrochemical techniques like linear polarization resistance, electrochemical impedance spectroscopy and polarization curves. The Aloe-Vera shows that the optimal concentration (100 ppm) is considered the ideal to decrease the corrosion process, getting a 90% of inhibitor efficiency. Finally, the Aloe-Vera can be considered as mixed type inhibitor under these experimental conditions.
