Great Loss

Steel constructions located in marine environments are exposed to more serious corrosion than in other environments, which result in great loss in lives and economy. So it is very important to carry out research work on the influence factor and mechanism of marine corrosion with necessary methods. In this paper, influence factors in marine environment of steels were discussed, the corrosion mechanism of five different zones in marine environment was summarized and the progress of research methods for marine corrosion was reviewed.

Corrosion Simulation

A set of modified marine corrosion simulation test device was designed in this study according to the characteristics of the natural marine environment, in order to study the corrosion behavior of steel materials. The natural corrosive marine environment could be simulated indoors by the device, which had advantages such as sea water self-circulation, stable wave, multi-level adjustable amplitude and frequency and so on. Components modeling, overall assembly and motion simulation were carried out by UG program, and the interference among the various components, limit position of movement and motion parameters were analyzed, effectively avoiding the problems that may arise during processing, manufacturing and assembly process.

Loss Method

Different zones of the marine environment were simulated by a designed marine corrosion test device in laboratory, through which the corrosion rate was tested by weight loss method applying separate specimens and electrically connected specimens, separately, and the test data were compared with those by seawater exposure method. The results showed that the corrosion in splash zone was the most severe whether for separate specimens or electrically connected specimens, and for the latter, the experimental data were more reasonable to simulate a continuous marine structure throughout the different zones in marine environment. The feasibility and reliability of the simulation device and the experiment method were also verified.

Doped Polyaniline

Different polyaniline micro/nanostructures were prepared in by oxidative polymerization doped with different acids like citric acid (C6H8O7), H3PO4 and HCl. The samples were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and UV–Visible spectral techniques. The rod-like composites, microspheres and nanofiber of polyaniline could be synthesized by different doting. The corrosion studies were carried out on steel plates coated with epoxy coatings containing polyaniline prepared with acid doping and no acid doing. Corrosion protection of these epoxy coatings containing prepared polyaniline (PANI) on steel was studied by Tafel polarization test in 3.5wt% sodium chloride (NaCl) aqueous solution. The results indicated that coatings prepared from acid doped polyaniline particles were found to exhibit excellent corrosion resistance much superior to no acid doped PANI in aggressive environments, and the epoxy coating containing PANI obtained in HCl doping had the best performance of the corrosion protection in all systems under investigation. The possible protective mechanism of PANI was discussed.
