Combatting Rudder Erosion with Cavitation-Resistant Coating

Cavitation erosion of the container ship rudder can occur as a result of high-speed sailing and supersizing. The coated surfaces of the rudder can be damaged, leading to vibration during sailing and difficulties with ship control. A major factor in determining the lifetime of the rudder, cavitation erosion has become a significant problem in the high-speed container ship industry. This article reports on the findings of a series of cavitation–resistance tests to identify test methods that effectively simulate cavitation behavior and classify cavitation and erosion resistance grade of the candidate materials. A vibratory test (ASTM G32) was compared with a cavitating liquid jet test (ASTM G134), and the vibratory test was found to be more effective for evaluating resistance of organize coatings due to its reproducibility and sensitivity.
