Abstract

Electrocodeposition of alumina nanoparticles with copper onto nickel substrate was prepared through the potentiostatic method. The codeposited films were obtained at different nanoparticle concentrations: 5, 10, 15, 20 and 25 gL-1. The corrosion behaviour of codeposited films has been observed by introducing them in different corrosive environments: 0.5 M H2SO4, HCl and HNO3 solutions. The corrosion study has been realized using the linear polarization method. The corrosion rate and polarisation resistance values were obtained from the Tafel curves. The highest concentration of alumina nanoparticles had increased the corrosion resistance of Cu-Al2O3 codeposited films. Also, in order to confirm these results, the gravimetric parameter was calculated by means of the mass loss method.
