Flame-Sprayed Copper Alloy Coating for Underwater Service: Corrosion Consideration
Abstract
The Copperlok Coating is a new method of applying copper and copper/nickel to a hulls surface for anti-fouling purposes. The process involves the thermal spraying of a copper nickel alloy onto a specially modified epoxy resin base coat. The alloy in wire form is melted by an oxyacetylene flame, atomized by compressed air and the molten particles are propelled to the surface where they form a strong mechanical bond. The coating can be built up to practical thicknesses of 10 to 12 mils which data shows should last 15 to 20 years on ships where hull speed is in the range of 8 to 12 knots. Other applications such as off shore structures, power plants and heat transfer surfaces will be presented with slides. The process and economic factors will be discussed. Samples of the coating will be available for inspection.
