Effects of Nano-sized Titanium Powder on the Anti-corrosion Property of Epoxy Coatings on Steel

Because of the existence of corrosion media such as chlorine, serious corrosion attacks ships, offshore and marine structure. Scholars worldwide have been long committed to the research of marine corrosion and development of anti-corrosion agents, and have achieved remarkable results. But so far, the conventional ocean coating inevitably makes microholes or microcracks between the additive and adhesive due to the physical or van der Waals force interactions between the packing and the binder, which provides a channel used to help the corrosion media reach the surface of the protected metal. Therefore, the corrosion resistance of common coating is reduced.
