30CrMnSiNi2A钢在模拟油箱积水环境中的腐蚀行为研究
通过分析探讨腐蚀面积、腐蚀失重速率、模拟油箱积水中的溶解氧含量和pH值、材料表面腐蚀电位等变化,研究了30CrMnSiNi2A高强钢在模拟油箱积水环境中的腐蚀行为。研究发现：30CrMnSiNi2A高强钢在模拟油箱积水中的腐蚀可分为三个阶段：快速腐蚀阶段（0～24h）,腐蚀面积小,腐蚀速率快;中速腐蚀阶段（24～168h）,腐蚀面积大,腐蚀速率相对减慢;慢速腐蚀阶段（168～480h）,发生全面腐蚀,腐蚀产物的大面积覆盖使得腐蚀速率缓慢。随着腐蚀的进行,模拟油箱积水中的溶解氧含量从开始的逐渐减少到保持稳定;pH值从开始的迅速增大到小幅度波动变化;腐蚀电位在整个腐蚀过程中呈指数函数递减变化。另外...

| Notes | 11-1800/TB 30CrMnSiNi2A steel; simulated tank water; corrosion HUANG Yi,LIU Hui-cong,ZHU Li-qun,LI Wei-ping, LIU Jian-zhong,YE Xu-bin（1 Key Laboratory of Aerospace Materials and Performance（Ministry of Education）,School of Materials Science and Engineering,Beihang University,Beijing 100191,China;2 Beijing Institute of Aeronautical Materials,Beijing 100095,China） The environmental conditions of aircraft tank water was simulated to study the corrosion behavior and characteristic of 30CrMnSiNi2A steel by corrosion area,corrosion mass loss rate,content of dissolved oxygen and pH in simulated tank water,corrosion potential of high-strength steel and so on.The results indicated that the corrosion process of 30CrMnSiNi2A steel in the simulated tank water was divided into three states： rapid corrosion stage came from 0h to 24h in which corrosion area was small and corrosion rate was fast;medium corrosion stage came from 24h to 168h in which most of the area was corroded and corrosion rate slowed down;slow corrosion stag |
