摘要
由于深海海洋环境的复杂性,深海油气开采等海洋工程装备长期承受海水侵蚀和化学腐蚀等问题。总体阐述了钢结构材料的湿硫化氢和海水腐蚀的特点及机理;针对耐硫化氢和耐海水腐蚀涂层,从目前涂层制备技术、涂层性能等方面进行了归纳和总结;总结了常见金属毒性效应和海洋生物友好性评价方法,可为绿色环保涂层配方成分设计以及应用风险评估提供技术支撑。
Due to the complexity of the deep-sea marine environment, offshore engineering equipment such as deep-sea oil and gas exploitation has suffered from seawater erosion and chemical corrosion for a long time. In this work, the characteristics and mechanism of wet hydrogen sulfide and seawater corrosion of steel structure materials were generally described. For hydrogen sulfide-resistant and seawater corrosion-resistant coatings, the current researches of the coating preparation technology and coating performance were summarized and summarized. Furthermore, the toxicity effects of common metals and the evaluation methods of marine biological friendliness were summarized, which could provide technical support for the design of green coating formulation components and application risk assessment.
