... expressed in terms of a threshold voltage below which cratering does not occur. As shown in Table 7 , zinc-coated surfaces have a lower cratering threshold voltage than bare steel and hence are more prone to cratering ( Ref 20 ). Although cratering can be avoided by reducing the voltage applied during e...

... higher ( Ref 5 ). In this case, zinc becomes a noble coating instead of a sacrificial coating and induces pitting of the bare steel. In seawater, zinc coatings corrode at approximately 181 g/m 2 /yr (0.59 oz/ft 2 /yr) or 1 mil/yr (25.4 μm/yr). Fig. 4 Effect of pH value on the corrosion of zinc...

... similarly to carbon steel. This behavior has long been recognized, and the use of bare, unpainted weathering steel when the yearly average time of wetness exceeds 60% is not recommended ( Ref 16 ). Another environment that is contraindicated for weathering steel is when the chloride level exceeds 0.5 mg...
