Sensitivity of the Ni-W nanocomposite doped amorphous nano-SiO2 particles to the electrolysis pH
Résumé
In spite of the nanoscale coatings progress, the effect of bath pH on nano silica zeta potential, surface morphology and electrochemical behavior of pulse electroplated Ni-W/SiO2 nanocomposite from citrate-analysis shows that the nanocomposite pact and with finer grain size. Corrosion resistance and electrochemical behavior into 3% NaCl media were discussed. The enhancement of the Ni-W/SiO2 nanocomposite has been referred to the mechanism of the formation of the nanoparticles adions double layer.
