MGPS용 알루미늄 양극의 인가전류와 유속에 따른 특성

Aluminum anode of marine growth protecting system for ship is installed in sea chest or sea water strainer. The Al anode is connected to a control panel that feeds a current to the anode. The dissolved ions produced by the anode are transferred in sea water, spreads through the sea water pipe system and creates a protective film in the pipelines. Thereby, corrosion significantly is reduced pipeline system. Accordingly, in this research, we evaluated influence of applied current and flow velocity on electrochemical characteristics of Al anode for MGPS. Based on the results of the erosion- cavitation experiments, damage rate increased greatly until 120 min. of the experimental time and decreased a little at the point of 180 min. where pit grew and merging occurred but showed a tendency of steadily increasing consumption rates.
