腐蚀,特别是海洋环境中发生的点蚀,导致材料服役寿命锐减并造成巨大的经济损失甚至环境破坏和灾难事故.在过去的十年中,针对材料在含氯化物水基环境的腐蚀行为开展了大量的研究工作.在此,综述从金属整体材料到包括有机涂层、金属及其合金或化合物涂层在内的表面处理的失效机理以及提高材料耐腐蚀性能和耐腐蚀?磨损性能的最新研究进展.其中,重点阐述周期性层片结构(PLSs),该组织无论是存在于金属整体材料或是表面涂层中,不管是在腐蚀或腐蚀?磨损过程中都展现出优越的抗腐蚀性能.基于不同尺寸、不同模型的数值仿真可加深对氯离子环境中的腐蚀或腐蚀?磨损过程的理解,并根据实验结果与数值仿真,着重分析PLSs以微电偶腐蚀占主导的腐蚀机理.总结各种腐蚀?磨损试验设备.展望未来的研究趋势,期待未来能够提供基于防腐蚀方法学设计的PLS的基本应用.“,”Corrosion, more specifically, pitting corrosion happening extremely in marine environments, leads to lifespan of materials drastically decreasing in service, which causes enormous economic loss and even environmental disaster and casualties. In the past decade, increasing efforts have been made to study the corrosion behaviors of materials in chloride-containing aqueous environments. Herein, this work provides an overview of recent progress in understanding the degradation mechanism and improving the corrosion resistance and corrosion-wear resistance of materials from bulk metal to surface treatment involving organic coating, metal and its alloy or compound coating. The particular emphasis is given to the periodic layered structures (PLSs), whose anti-corrosion properties outperformed others to some extent, wherever in terms of bulk metal or surface treatment, regardless of aggressive environment (corrosion or corrosion-wear conditions). Numerical simulation based on kinds of models at different scales is introduced to deeply understand the process of corrosion and/or corrosion-wear in chloride-containing aqueous environment. Combined experimental result with numerical simulation, the micro-galvanic corrosion dominated degradation mechanism of PLSs is critically analyzed. Types of setups to realize corrosion-wear in laboratory are also summarized. At last, future research and development are prospected, offering to develop a basic application of PLSs designed by corrosion protection methodology in the near future.
