Abstract
The invention relates to a method and apparatus for the application of a thin film coating of material onto a surface of an article which is to be exposed to aqueous conditions such as when in the sea or rivers. The invention allows for the formation of a coating which is resistant to fouling and which coating can be formed of materials which have significantly less adverse effect on the quality of the water in which the article is placed in comparison to conventional coating types.
Claims8
A method of protecting a surface of an article against aquatic biofouling, said method comprising:
- placing the article on a holder for rotation in a chamber while applying a thin film coating within said chamber onto said surface to form a protective external coating thereon;
- wherein said method comprises the steps of rotating the holder with the article placed thereon;
- applying a bias to the said article, applying a layer of silicon material on said surface from a solid target of silicon material;
- applying a layer of SiO2 on top of the silicon material layer and then
- applying, simultaneously, material from the solid silicon target of material and material from gases in the form of HMDSO and O2 introduced into the said chamber, to form the final and external layer of the said coating and the silicon material is deposited from the solid target using closed field unbalanced magnetron sputtering and operating an electrode in the chamber to assist in the breaking down of gases as the said final and external layer of the coating is formed.
