摘要: Abstract In order to study cathodic protection technology for steel structures in an arctic seawater, the effects of alloying elements, surface finishing and seawater temperatures on anode performance commercial grade Al anodes were investigated by measuring anodic polarization artificial seawater. The containing Zn. Mg suffered pitting as potential became more noble at 273 K. Pitting was prevented increasing contents alloy. This resulted improved characteristics low temperature is explained terms a decrease with consequent active dissolution without passivation pitting.
