To develop thermal spray coatings with corrosion protection and anti-fouling properties, aluminum-copper alloy powders, aluminum-copper blend powders, aluminum-zinc blend powders and a zinc powder are flame sprayed onto a steel substrate and the coatings are immersed in the sea and regularly monitored. Some of the substrates are treated with an aluminum under-coat prior to the spraying of the above-mentioned coatings. <br> The aluminum-copper alloy coatings have poor anti-fouling properties, and the substrate starts to rust after a few months’ immersion in the sea. Although the anti-fouling properties of the aluminum-copper blend coating is improved with increasing copper content, rusting of the steel substrate occurs on the coating with high copper content. <br> The zinc coatings and the aluminum-zinc blend coatings with high zinc content possess both corrosion protection and anti-fouling properties. It was found that the zinc phase in the aluminum-zinc blend coatings preferentially react with the sea water and the content of the metallic zinc phase in the coatings decreases with the immersion time of the coatings in the sea. The aluminum under-coat has little influence on the anti-fouling properties of the aluminum-copper blend coatings and the aluminum-zinc blend coatings, while the formation of the white rust on the coatings is enhanced.
