Caracterización morfológica de cobre depositado por electrólisis influenciado por presencia de iones cloruros

Abstract: RESUMEN En el presente trabajo se estudia el efecto de la densidad de corriente sobre la morfología del cobre depositado por electrólisis desde una solución ácida de sulfato de cobre en presencia y ausencia de iones cloruros como impurezas. Para ello, técnicas de cronopotenciometría y microscopía electrónica de barrido son utilizadas. El estudio revela que, para ambas situaciones en presencia y ausencia de iones cloruros, los perfiles temporales del potencial catódico son desplazados en dirección catódica con … Show more

“…It was also ensured that metallic coatings were obtained using the potential corresponding to the metal reduction region during the electrodeposition process. Previous studies have demonstrated that using EGbased electrolytes can result in the deposition of Cu alloy coatings, as well as pure metallic Ni, but only on substrates other than 304 SS [29,30].…”

“…The XRD pattern of the Cu coating corresponds to metallic Cu (JCPDS card no. 04-0836, letter C), with peaks located at 43.3 • , 50.4 • , and 74.8 • , corresponding to the planes (111), (200), and (220) of Cu, respectively [30]. The XRD patterns of the Ni coating, letter D, show the characteristic reflections of Ni (JCPDS card no.…”
