Abstract:
      Objective To research influences of exposure position and height on corrosion of steels in splash zone. Methods Exposure test was carried out in the splash zone of seawater. Results Corrosion results of five kinds of steel in Qingdao and Sanya were obtained. Conclusion Large difference exists in the corrosion range and peak value of corrosion rate when steels are exposed in different test sites of sea areas because of different environmental conditions. Meanwhile, in the same test site, different exposure position and conditions can cause different range of splash zone and peak value of corrosion rate.
