The component parts of the shell plate of a ship are steel. but the screw propeller or the bow thruster is a compound of bronze, nickel and aluminum. On account of the these different components between metals of the shell plate, the screw propeller and the bow thruster, which are underwater, the shell plate of a ship is corroded by the action of ionization.
Authors investigated the corrosion loss of the zinc anodes which were attached to the bottom shell of the training ship Kaya for about two years.
The obtained results were as follows:
1. In case of the shell plate the difference of the corrosion loss according to port and starboard was almost nothing. But the corrosion loss of the forward part was more than that of the aftward part.
2. There was little difference in the corrosion loss between the forward and the aftward part on the bilge keel.
3. The corrosion loss of the fore, midship and aft part on the false keel were 24.7%, 22.4% and 23.9%
respectively.
4. The corrosion loss of the fore and the aft part on the false keel was more than that of the midship part.
5. The corrosion loss of the bow thruster was greater than any other parts.
6. The nearer the zinc anode to the screw propeller the more the corrosion loss on the stern frame, and the situation was also same as on the rudder.
