电力设施生物污损腐蚀与热喷涂表面防护研究进展

海洋生物容易附着和生长于沿海电力设施装备表面，其代谢过程及产物能够引起表面金属材料的腐蚀加速、电力设施的老化破损，进而造成巨大的危害和经济损失，因此降低和抑制电力设施表面生物污损的涂层防污技术有着重要的研究与应用价值。基于热喷涂的防污涂层制备技术是防生物污损腐蚀的重要方法之一，是未来将研究工作应用于实际的重要方向。截至目前，有关电力设施装备生物腐蚀现状和热喷涂表面防护的研究进展尚未见报道，这里将对电力设施装备生物污损腐蚀现状、应用案例及热喷涂防污措施研究进展进行归纳整理，并进行系统性综述。首先介绍了不同深度近海区域电力装备生物污损和腐蚀的现状、特点，引用了近年来典型电力设备涂装防污损的技术方案和应用案例，然后依据不同的技术特点和发展趋向，对近10年来热喷涂制备的复合防污涂层研究进展进行了综述，分析其在沿海电力设施防护方面的应用前景，以期为未来电力设施防污损等研究工作起到一定指引作用。

Research Progress on Biological Fouling and Corrosion and Thermal Spraying Surface Protection of Power Facilities

Marine organisms are inclined to attach and grow on the surface of coastal power facilities, and their metabolic process and products lead to accelerated corrosion of metal surfaces and aging damage of power facilities, resulting in potential harm and economic loss. Therefore, anti-fouling coating techniques that can reduce and inhibit biological fouling on the surface of power facilities are of crucial research and application value. The preparation of anti-fouling coating by thermal spraying is one of the important methods to prevent biological fouling and corrosion and also an important direction to apply research work to practice in the future. Up to now, the research progress of biological corrosion status of power facilities and equipment and thermal spraying surface protection has not been reported. The current situation of biological fouling corrosion and the research progress of thermal spraying anti-fouling measures of power facilities and equipment were summarized in order to give a timely and comprehensive review. Firstly, the present situation of biological fouling and corrosion characteristics on power equipment in different coastal regions was introduced, typical application cases of anti-fouling coatings for different power facilities in recent years were cited, and then the research progress of the thermal spraying composite anti-fouling coating for nearly 10 years was exclusively reviewed according to different technical characteristics and developing trends. Additionally, the application prospect in coastal power facility protection was also analyzed, so as to provide important guidance for future research in the related fields.
