摘要
Abstract
The environmental conditions of aircraft tank water was simulated to study the corrosion be-havior 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 wa-ter was divided into three states- rapid corrosion stage came from Oh 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 stage came from 168h to 480h in which all of the area was corroded and corrosion rate was slow. With time going on, content of dissolved oxygen gradually reduced at first and then kept steady; pH value rapidly increased at first and then fluctuated within a narrow range; corrosion potential changed as decreasing exponential func-tion. In addition, EIS and Tafel polarization curves indicated that corrosion rate of 30CrMnSiNi2A steel at three characteristic pH(4. 2,4. 8,5. 2) decreased with pH value increasing.关键词
