摘　　要：目的研究喷气偏流板的腐蚀损伤。方法以喷气偏流板装置结构特点入手,通过对腐蚀的分类及产生原因分析,研究了喷气偏流板装置的腐蚀损伤特点。结果冷却面板存在连接处的剥蚀、面板内部海水流道点蚀和防滑涂层高温腐蚀等三种腐蚀情况,运动执行机构在各连接处容易发生缝隙腐蚀。结论提出了喷气偏流装置在生产加工和日常使用维护中的腐蚀防护措施。Objective to study the corrosion damage of the jet blast deflector. Methods Based on the structure characteristics of the Jet blast deflector, the classification method and reason for corrosion were analyzed, and the properties of corrosion damage of jet blast deflector were studied. Results there were exfoliation corrosion in the connecting parts of the flats, pitting in the panel, high-temperature corrosion in the antiskid coating, and crevice corrosion in the motion actuators. Conclusion the characteristics of corrosion were discussed, and the corrosion protective measures in production and routine maintenance were proposed.
