Actualmente existe un gran interés por el empleo de fuentes de energía renovables como el biodiesel, por poseer grandes ventajas con mínimos daños al ambiente. Sin embargo, el manejo de biocombustibles puede ocasionar problemas de corrosión por incompatibilidad del mismo con los materiales metálicos. En el presente trabajo se pretende evaluar la susceptibilidad frente a la corrosión en biodiesel, de un acero inoxidable austenítico, a partir de estudios electroquímicos. Se efectuaron medidas del potencial de circuito abierto en función del tiempo, polarizaciones potenciodinámicas, ensayos de espectroscopía de impedancia electroquímica y de voltametría cíclica. Los resultados obtenidos permiten señalar un buen comportamiento frente a la corrosión del acero inoxidable estudiado, en biodiesel obtenido a partir de aceite de soja
Essentially there is a great interest in the use of renewable energy sources such as biodiesel, attributable to great advantages with minimal damage to the environment. However, handling of biofuels can lead to corrosion problems due to the incompatibility of biodiesel with metallic materials. In the present work is intended to evaluate the corrosion susceptibility in biodiesel of an austenitic stainless steel using electrochemical techniques. Measures at open circuit potential versus time, potentiodynamic polarization curves, electrochemical impedance spectroscopy and cyclic voltammetry assays were performed. The results show a good resistance to corrosion of stainless steel tested in biodiesel obtained from soybean oil
