Aluminum tripolyphosphate coating had a good anticorrosive performance. After total immersion, there was no rust, blister, crack, or flake that occurred on coating. Compared to the epoxy antirust painted samples, the studied coatings exhibited better self-healing and anticorrosive feature. When the water has penetrated into the coating, the pigments based on phosphate anions can release phosphates to form a protective layer on the metal substrate. The layer prevents the access of water and corrosion reaction to protect substrate.
