THERMAL SPRAY FOR CORROSION CONTROL: A COMPETITIVE EDGE FOR COMMERCIAL SHIPBUILDING

Thermal spraying of steel with aluminium to protect it from corrosion is a technology that has been proven to work in the marine environment. The thermal spray coating system includes a paint sealer that is applied over the thermally sprayed aluminium: this extends the service life of the coating, and provides colour to the end product. The thermal spray system protects steel both through the principle of isolation (as in painting) and galvanization (as in galvanizing). With this dual protection mechanism, steel is protected from corrosion even when the coating is damaged. The thermal sprayed aluminum coating system has proven to be the most cost- effective corrosion protection system for the marine environment. Until recently, however, the initial cost of application has limited its use for general application. Today a new arc spray technology has reduced the application cost of thermal spraying aluminium to below that of painting. Commercial shipbuilders could use this technology to enhance their market position in the marine industry.
