초록
Aluminum acts as sacrificial anode and corrosion protection with Al2O3 formation. If the same current on material forAl ships with steel ships supplies, the more hydrogen would be occurred, that result is bring about over-protection. For thisreason, the damage by hydrogen embrittlement leads to the serious accident. In this study, we evaluate electrochemical behaviorwith rotation speed of 5083-H116 Al alloy material for Al ship in seawater. To examine the electrochemical characteristics withrotation speed and its effects on performance, experiments were conducted at four rotation speed. Results of experiments, thecorrosion current density and damage were increased by applying the rotation speed compared to static state.
