When ships navigate on the ocean for a long time, a fouling effect always occurs on the ship body below the waterline. The fouling effect means that the ocean lives, such as diatoms, barnacles, slime and etc. adhere on the surface of the ship body, especially on the bilge of ships. This adhesion phenomenon will increase the ship-cruising resistance, the fuel-waste and decrease the ship-cruising velocity without cleaning away these adhesive ocean lives. In order to increase the lifespan of ships, therefore, it is necessary to proceed with the anti-fouling or the anti-parasitic process. The aim of this project is to design and to study an advanced nano-thin film coating, which has an anti-parasitic effect of the ship body for resisting the breeding of ocean lives. The systematically variation of nano-thin film coatings in aspect of manufacturing parameters and surface modification of materials for ships will be studied by the microstructural observations. Furthermore, the briny immersion test will be proceeded to evaluate the anti-parasitic effect of the coatings. After the above-mentioned tests, the anti-parasitic effect and the performance of the nano-thin film coatings on the bilge will be discussed and concluded for the manufacturing of ship body. |
