1.- Hacer la grfica E vs i y la grfica E vs log|i|

2.- Identificar las tres zonas (activa, pasiva y transpasiva) en el grfico. As mismo obtener los diferentes parmetros

3.- Hallar la densidad de corrosin. Transformar la corriente de corrosin en unidades mpyDel grafico E vs log|i|; podemos obtener las pendientes de Tafel y calcular:

Del grafico E vs i podemos calcular para un ||< 10mV la Rp. Siendo esta Rp = 1099.2 .cm2

Finalmente tenemos:

4.- Cmo influir el valor del aumento de potencial con el tiempo en la curva de polarizacin?Grafica E (mV) vs i (mA/cm2)

Del grafico se puede observar que en lecturas rpidas (2.0 mV/s) la grfica de polarizacin se encuentra sobre las dems; mientras que en la de lectura ms lenta (0.5mV/s) se encuentran debajo abajo.
