ANTICORROSION METHOD FOR HIGH SPEED SHIP

摘要

PROBLEM TO BE SOLVED: To provide an anticorrosion method for a high speed ship capable of surely preventing corrosion. SOLUTION: This anticorrosion method is for a high speed ship having a hydrofoil 3 constituted with stainless steel attached at the bottom of an aluminum hull 2. Paint is applied to a prescribed surface of the hull 2 and the surface of the hydrofoil 3. An insulation sheet is inserted at an attached part of the hydrofoil 3 to the hull 2, and an insulating treatment is also applied to connecting parts of them, Lower sacrificial positive electrodes 21A are installed on keel parts 2b of the hull 2. Upper sacrificial positive electrodes 21B are installed on upper side locations of the hull 2.
