A Novel Approach to the Synthesis of Alloy: PEG400 Containing ZnNi and ZnNiCr Alloy Coatings and Their Anticorrosion Performance

ZnNi and ZnNiCr alloy coatings were electrochemically deposited onto carbon steel (CS) in the presence of PEG 400 for the first time. Scanning electron microscope (SEM) and energy-dispersive X-ray (EDX) analyses showed that polyethylene glycol (PEG) was incorporated into ZnNi and ZnNiCr alloy coatin...

Description
Summary:ZnNi and ZnNiCr alloy coatings were electrochemically deposited onto carbon steel (CS) in the presence of PEG 400 for the first time. Scanning electron microscope (SEM) and energy-dispersive X-ray (EDX) analyses showed that polyethylene glycol (PEG) was incorporated into ZnNi and ZnNiCr alloy coatings. Although it contained active zinc, the corrosion resistance of all coatings increased as the exposure time to the corrosive environment increased, and all coatings exhibited Warburg impedance. Furthermore, Warburg coefficients were incredibly higher for PEG incorporated alloy coatings than for those without PEG, which was attributed to the filling of the pores by PEG in addition to the oxide layers formed on alloy surfaces.
