Abstract Scope The effect of incorporation of carbonaceous additives on morphology, composition, phase constitution and corrosion properties of Zn-5wt.%Co composite coatings was investigated. Two different sets of Zn-Co coating with varying amount of multi-walled carbon nanotubes (MWCNTs) and graphene oxide (GO) were electrodeposited over mild steel. The coatings contained a mixture of Zn and Zn10.63Co2.34 intermetallic phases, the relative fraction of which was highly sensitive to the amount of MWCNTs/GO added into the electrodeposition bath.Electrochemical impedance spectroscopy (EIS) and Tafel polarization studies revealed that with continued addition of MWCNTs/GO into the coatings, the corrosion current density first dropped to a minimum followed by an abrupt rise. This indicated that an ‘optimum’ additive amount is required for achieving high corrosion resistance performance. Based on long term impedance and weight loss measurement data, the corrosion mechanism, type of corrosion products and their relation to the phase fraction and additive amount will be discussed.
