Corrosion behaviour of Zinc or 55% Al Zn hot-dip coated steel in 0.5 m NaCl solution

Acomparative study on the anticorrosive behaviour of 55%Aluminum-Zincalloy and Zinc hot-dip coated carbon steel immersed in 0.5 mol/L NaCl solution was performed using DC (polarization curves) and AC (electrochemical impedance spectroscopy) techniques. Also, the corrosion products formed under these...
