摘要
目的验证海洋环境下硬膜水置换型缓蚀剂应用于军用飞机连接部位的有效性。方法采用功能渗透性试验、环境谱加速腐蚀对比试验对缓蚀剂性能进行评价,并通过在某型飞机典型结构部位的领先试用验证缓蚀剂的实际应用效果。结果缓蚀剂渗透率可达到85%。应用于军用飞机内部,对腐蚀的发展有明显的抑制作用,可显著延长腐蚀发生的时间。结论应用缓蚀剂作为腐蚀预防的有效手段,可在军用飞机维护中推广应用。
Objective To study the validity of the hard film water-displacing corrosion inhibitor which is used in the joint sections of military aircraft in marine environment. Methods The performance of corrosion inhibitor was evaluated through functional penetration test and environment spectrum accelerated corrosion contrast test,and the practical application effect was verified by the lead probation on typical structure sections of a certain aircraft. Results The penetration rate of the corrosion inhibitor was 85%. The applications of corrosion inhibitor in the military aircraft internal structures could effectively retard the development of corrosion,and postpone the occurrence time of corrosion. Conclusion The applications of corrosion inhibitor in the military aircraft maintenance as an effective means to prevent corrosion is valuable for popularization and application.
