摘　　要：紧固件作为工程设备结构联接的基础零件,其力学性能与耐久性能对设备各部件间的紧密连接起到决定性作用。钢材作为紧固件的主要材料,处于复杂海洋环境中时,会受到氧、Cl-等大量腐蚀介质的严重侵蚀,从而对工程设备的可靠使用造成巨大威胁。近年来,表面处理技术作为紧固件的主要防腐手段受到国内外学者广泛研究。本文对常用的紧固件表面防腐工艺(电镀、达克罗涂层、热浸锌、粉末渗锌)进行分类阐述,并对比评价其在海洋环境中使用的可行性。Fasteners as engineering equipment structural connection of basic parts,its mechanical properties and durability of the equipment between the components of the close connection plays a decisive role.Steel as the main material of fasteners,in the complex marine environment,will be-subject to oxygen,Cl and other corrosive media,serious erosion,thus posing a great threat to the reliable use of engineering equipment.In recent years,surface treatment technology as the main anti-corrosion means of fasteners has been widely studied by scholars at home and abroad.In this paper,the commonly used surface anti-corrosion processes of fasteners(electroplating,Dacromet coating,hot-dip zinc,thermal diffusion zinc)are classified and described,and the feasibility of their use in the marine environment is comparatively evaluated.
