“…[1][2][3][4] In general marine environment, most aggressive corrosion always occurs in the splash zone where the steels may face the dry/wet alternate environment with high salt concentration. 5,6 Therefore, many efforts were applied for the protection of reinforced steels in concrete structures within splash zones. Up to now, many types of corrosion protection approaches have been developed, including using high-performance concrete, covering layers and silane penetrant.…”

This paper presents a novel system to protect the reinforced steels from corrosion in the underwater zone by removal of the dissolved oxygen. The factors that influence the corrosion processes such as the pH value and the dissolved oxygen concentration were monitored for 48 hours in this system. And the effects of the dissolved oxygen consumption under different output currents and flow rates were compared. Then the corrosion rate of the steels under protection using this system was monitored for 100 hours. At last, a contrastive analysis was conducted between the scanning electron microscope surface morphologies of two bare steel specimens immersed in the underwater zone for 30 days with and without protection. The results showed that the pH value would increase and the dissolved oxygen concentration would decrease in the novel system, which is beneficial to protect the steels. The dissolved oxygen concentration could be reduced to a low value when the output current and the flow rate are appropriate. Steels could be well protected in the system presented in the paper.

Seawater is highly corrosive, and the alternating dry and wet environment can cause severe corrosion in metal equipment. Moreover, marine equipment is also seriously affected by marine biofouling. These harsh conditions pose a serious threat to the integrity of marine equipment as well as their associated maritime activities and necessitate the development of effective coatings to minimize damage to the equipment. Urushiol titanium polymer/acrylic resin (UTP/AR) composite materials were developed. Then, marine anti-corrosion and antifouling coatings were prepared from the UTP/AR composite materials using rosin-modified Cu 2 O as an antifoulant. The composite coating with a UTP:AR mass ratio of 1:1 (UTP/AR3) showed the best chemical resistance and light aging resistance. UTP/AR3 also exhibited a good corrosion current density (2.009 × 10 −7 A cm −2 ) and corrosion potential (−0.5007 V), further indicating that the UTP/AR composite coatings have excellent anti-corrosive properties. Marine field tests showed that the UTP/AR/Cu 2 O composite coatings with rosin-modified Cu 2 O contents less than 20% showed stable, longterm antifouling performance after immersion in seawater for 360 day. Briefly, the UTP/AR/Cu 2 O composite coatings have broad application prospects in the marine industry for materials in the spray splash zone.
