Abstract: 
This study is related to premature corrosion that appeared repeatedly in some vessels at the contact between the main shaft casing and the main shaft shutter due to galvanic interaction. Two preventive strategies were found feasible: application of a silicone based coating, and alternatively plating with duplex stainless steel. These potential solutions were evaluated by classical corrosion tests in a salt spray chamber, and by electrochemical corrosion tests addressing the galvanic effect. It was concluded that the option involving the coating provides high performance against the current problem.
