Behavior of Ni/Al2O3 Nanocomposite Thin Layers in Corroding Environment

Abstract

This paper investigates the effects of adding alumina nanoparticles in the electrolyte bath on surface topomorphologies and structure of electrodeposited nickel. The influence on the corrosion process in NaCl solutions having various concentration was investigated by using impedance spectroscopy. The experimental data indicates the beneficial roles of alumina nanoparticles on Ni/Al₂O₃ nanocomposite thin films. The structure of electrocodeposited nanocomposite thin films was investigated by XRD and SEM techniques.
