En la presente investigación estudiará la corrosión de biomateriales de aleaciones metálicas biocompatibles en relación al comportamiento de la degradación química o corrosión de estas aleaciones cuando son expuestos a soluciones sintéticas fisiológicas
The performance of different Cu-based coins in artificial sweat was evaluated. The electrochemical behavior of the coins was
determined by potentiodynamic polarization curves, linear polarization resistance, and electrochemical impedance spectroscopy.
Regardless of the chemical composition of the Cu-based coins, they showed similar polarization cur...
In this work we proposed to evaluate the corrosion resistance of four different alloys by electrochemical techniques, a binary alloy
Cu10Al, and three ternary alloys Cu10Al-𝑥Ag (𝑥 = 5, 10, and 15wt.%) to be used like biomaterials in dental application. Biomaterials
proposed were tested in artificial saliva at 37∘C for 48 h. In addition, pure metals...

... oxidized form of Ti is then dominant), bearing in mind that the pH of the SBF was kept constant at 7.4, just as the corresponding Pourbaix diagram for Ti suggests [45]. This fact is responsible of the bioinert nature of this alloy [46][47][48][49]. However, when the alloy surface is anodically polarized it shows a continuous increase in current density as polarization from E corr increases, indicating that the formed oxide layer becomes unstable and dissolves in contact with body fluids; this fact has also been reported in previous works [48]. ...
