Abstract

The specific strength of Al ships is higher than that of steel ships. They are capable of high speed, have increased load capacities, greater ease of recycling, and high anticorrosion properties. We report a number of electrochemical experiments undertaken to determine the optimum corrosion protection potential conditions for MIG welded for protecting 5083-H116 (Al-Mg alloy) in natural seawater. Cathodic polarization results in concentration polarization by dissolved oxygen reduction and activation polarization as a result of hydrogen generation. The maximum tensile strength, elongation and time-to-fracture decreased when the potential shifted beyond the potential range of - 1.2. V to - 0.7. V in either the anodic or cathodic directions.
