Electrodeposición de cobalto sobre oro a partir de un baño electrolítico a base de bitartrato.
Resumen
En el presente trabajo realizamos un estudio voltamperométrico del proceso de depósito de cobalto sobre un substrato de oro a partir de un baño electrolito de base de bitartratos y de composición CoCl2 0.01 M + KC4H5O6 0.05 M. Los resultados indican que, a partir del sistema estudiado, el cobalto se puede electro depositar en el rango de potencial ubicado entre -0.5 a -0.9 V. El comportamiento de la corriente de pico vs la velocidad de barrido1/2, sugiere un proceso controlado por difusión. En donde el valor del coeficiente de difusión es 8.2x10-8 cm2 s-1
