The corrosion characteristics of various steels used by ocean wave energy equipment in sea water are investigated by electrochemical tests in this paper. The electrochemical experiments are carried out to research the corrosion rules of Q235, 20# steel, 16Mn and X42 through contrast experiments. Polarization curves and electrochemical impedance spectroscopy (EIS) are got by electrochemical workstation. Corrosion rates and corrosion potentials are analyzed from the polarization curves, and corrosion rules are founded. In addition, EIS is analyzed, and the analysis results are consistent with the results of polarization curves.

The corrosion characteristics of mild steel in real sea water are investigated by electrochemical test in this paper. Polarization curves and electrochemical impedance spectroscopy (EIS) are got by electrochemical workstation. From polarization curves, it is found that the corrosion rate rises at the initial period, and it becomes the highest on the 3rd day, then drops, and it tends to be stable after about 15 days, which is confirmed by EIS. In addition, the experiments also show that the corrosion layer can suppress the corrosion process. The electrochemical corrosiveness of the mild steel is analyzed in this study, and it lays a foundation for anticorrosion technology research.

Generation Unit

Energy resources of offshore wind and ocean wave are clean, renewable and abundant. Various technologies have been developed to utilize the two kinds of energy separately. This paper presents the principle of an integrated generation unit for offshore wind power and ocean wave energy. The principle of the unit includes that: The wind rotor with retractable blades and the 3-DOF (degrees of freedom) mechanism with the hemispherical oscillating body are used to collect the irregular wind and wave power, respectively; The energy conversion devices (ECDs) are utilized to convert mechanical energy from both the wind rotor and the 3-DOF mechanism into hydraulic energy; The hydraulic energy is used to drive the hydraulic motors and electrical generators to produce electricity. Some analyses and experiments of the unit is conducted.
