COATING METHOD FOR PREVENTION OF ABRASION BY CAVITATION

摘要

The present invention relates to a coating method to prevent abrasion by cavitation. More specifically, in accordance to the coating method, the abrasion by cavitation caused by liquid flow such as a propeller′s movements, a screw, and a rudder of a ship, is prevented. The coating method comprises: a surface treating step of performing a strike process or a plating process on the surface of a material using inorganic metal; and a plurality of layer coating step of coating the material having the treated surface to form a plurality of layers. Adhesion between the material and a plurality of coating layers is increased; thus enhancing anti-abrasion properties. High rigidity can be maintained using carbon nanotubes as an additive to the plurality of coating layers.
