The influence of pH on properties of Ni-Co coating — •Golsa Rassaie1, Hida Rassaie2, and Sina Sadreddini2 — 1Department of engineering management,upm university, Malaysia. — 2Department of Materials Science and Engineering, Science and Research Branch, Islamic Azad University, Tehran, Iran.
Electrodeposited Nickel-Cobalt alloys are exposed to investigate the relationship between pH, Co content, microstructure and corrosion resistance. Direct current electrodeposition was applied to create compact coatings. The microstructural observations were performed with field emission scanning electron microscopy (FESEM). The amount of SiO2 was examined by Energy Dispersive Analysis of X-Ray (EDX) and crystalline structure was examined by X-Ray diffraction (XRD). The Corrosion behavior was evaluated through electrochemical impedance spectroscopy (EIS) and polarization techniques.
