摘要

目的针对某濒南海大型工程钢质紧固件腐蚀严重的问题,通过试验研究对比钢质紧固件的腐蚀防护技术。方法分别在钢质紧固件表面制备防护层膜,通过现场挂样试验和实验室环境模拟加速试验研究不同涂层的腐蚀行为,并采用电化学试验研究不同涂层在模拟条件下的失效机理。结果对现场试验、实验室加速试验和电化学阻抗测试数据进行分析,不同涂层紧固件的防腐效果排序为复合涂层>锌铝涂层>粉末渗锌≈热浸镀锌>电镀锌>氧化膜层保护。结论通过试验对比评价了紧固件6种表面处理技术的防腐性能,为濒海设备使用的紧固件防腐措施的选择提供了理论依据和技术支撑。
        Objective To study corrosion protection techniques for steel fasteners through experiment and comparison to solve the serious corrosion of steel fasteners for large engineering projects in the South China Sea. Methods The protective film was prepared on surface of steel fasteners. The corrosion behavior of different coatings was accelerated by in-situ sample test and laboratory environment simulation acceleration test. The failure mechanism of different coatings under simulated conditions was studied by electrochemistry test. Results Analysis of data of field test, laboratory acceleration test and electrochemical impedance test showed that the antiseptic effects of different coatings of fasteners were sorted as follows: composite coating > zinc and aluminum coating > powder zinc≈hot dip zinc plating>zinc plating>oxidation film layer protection. Conclusion The antiseptic properties of six surface treatment techniques for fasteners are evaluated by experiments. It provides theoretical basis and technical support for selection of anti-corrosion measures for fasteners used for equipment in the sea.
