Lithium and Cerium based sol-gel coatings for corrosion protection of AA2024-T3

Due to the demand of reducing the weight of aircrafts to reduce the carbon consumptions without compromising the mechanical properties, aluminium alloy AA2024-T3 has been widely applied in the aircrafts’ manufacture. However, the alloying elements which ensure the mechanical properties also could increase the susceptibility of localized...

Damage Estimation of a Ship's Hull using ICCP system Measurements

Most ocean-going ships are fitted with an impressed current cathodic protection (ICCP) system. The currents impressed by this system onto the seawater find their way to corroding parts of the ship’s hull, and prevent the hull from corroding. The electric field resulting from the currents around the ship is called the electric signature. This...

Active corrosion protection of aerospace aluminium alloys by lithium-leaching coatings

For decades, scientists and engineers are searching for a safe and environmentally friendly alternative for the toxic chromate corrosion inhibitors in active protective coatings for the protection of aerospace aluminium alloys. In this search many different compounds have been investigated as leachable corrosion inhibitor, but no alternative...
