| Abstract: | Ni-Fe amorphous alloy coatings are electrodeposited on aluminum foil in order to improve electromagnetic shielding performance. The additives and pH of electrobath as well as current density of electroplate were investigated. SEM analysis showed that a good quality deposit was obtained. The structure of deposits was investigated by XRD. The results showed that the electromagnetic shielding performance of the Ni-Fe amorphous alloy deposit was improved within both high and low frequency. |
