摘要
钢结构在海水中腐蚀损伤具有复杂性和多样性的特点,对其进行研究存在一定的挑战性。针对海洋工程装备的腐蚀问题,对钢结构在海水中的腐蚀机理、防腐寿命预测和评估进行概述。对比涂料防腐技术、金属涂层防腐技术、电化学防腐技术发现:国外有严格的国家环保法规,国内环保立法滞后,尤其涉及到高压低温环境中应用困难。
Corrosion damage of steel structures in seawater is characterized by complexity and diversity, and it is challenging to study it. Aiming at the corrosion problem of offshore engineering equipment, the corrosion mechanism of steel structure in seawater, anti-corrosion life prediction and evaluation are summarized.Compared with coating anticorrosive, metal coating anticorrosive and electrochemical anticorrosive technology,it is found that there are strict environmental protection laws in foreign countries, and the domestic environment-protecting law behind, especially involving the application difficulties in the high-pressure and low-temperature environment.
