PURPOSE:To easily and efficiently prevent the sticking of marine products to a propeller, by forming a thermally sprayed film of copper of a specific thickness on the external surface of a propeller structure for ships and applying sealing treatment to the above. CONSTITUTION:A thermally sprayed film of copper or copper alloy of 150-200mu thickness is formed on the external surface of a propeller structure for ships (stern tube bearing, propeller shaft, propeller). Further, as the thermal spraying material, that of >=about 99wt.% copper content is preferred. Subsequently, a synthetic-resin material having properties such as leachability, sea-water resistance, and wear resistance is allowed to adhere to the above-mentioned thermally sprayed film to 20-30mum thickness to apply sealing treatment. In this way, the treatment for preventing the sticking of marine products to a propeller for ships can be easily performed. |
