Abstract

Se evaluó una aleación Pb-Sn-Ca-Ag utilizada en la fabricación de rejillas para baterías de automóviles, específicamente, se evaluó el efecto de la temperatura, a 25, 35 y 45 °C, junto con el tiempo de inmersión en ácido sulfúrico al 0,5 M, de 0, 7 y 30 días, mediante espectroscopia de impedancia electroquímica. De acuerdo con los resultados, se obtuvo el comportamiento de la velocidad de corrosión. Adicionalmente, con las pruebas de DRX y MEB fue posible realizar un análisis de los productos de corrosión que se formaron durante el proceso de inmersión en ácido. Los resultados demostraron que la aleación Pb-Sn-Ca-Ag no es recomendable para elaborar rejillas utilizadas en la fabricación de baterías de automóvil.
