    从异常点入手开展封闭式贮存环境中的腐蚀失效分析

    Corrosion Failure Analysis in Closed Storage Environment Starting From Abnormal Points

    • 摘要: 本文对几种典型封闭式贮存环境中发生腐蚀失效的案例开展分析,采用宏微观特征观察、能谱分析和金相检查等方式,明确了腐蚀特征和腐蚀机理。在此基础上,通过总结归纳共性特点,提出在封闭式贮存条件下可能发生腐蚀失效,但其原因通常具有较强的隐蔽性,应从异常点入手,分析意外介质渗透及潜在的失效驱动力,探寻腐蚀失效的根源,有助于对贮存环境下发生失效的产品开展针对性分析。结果表明:腐蚀介质是零件产生腐蚀失效的必要起因,失效驱动力是推动腐蚀不断发展至宏观失效现象产生的能量来源。研究结果为加强贮存条件下的防腐工作提供参考意见。

       

      Abstract: Several typical cases of corrosion failure in closed storage environment were studied. Through macroscopic and microscopic feature observation, energy spectrum analysis and metallographic examination, the corrosion characteristics and mechanisms were determined. On this basis, the commonalities were summarized and generalized. It is put forward that corrosion failure may occur in closed storage environment, but the corrosion failure causes usually have strong concealment. Starting from abnormal points, accidental medium penetration and potential failure driving forces should be analyzed to explore the root causes of corrosion failure, which is conducive to conducting targeted analysis of product failure in storage. The results indicate that corrosive media are the necessary cause of corrosion failure, and failure driving forces are the energy source promoting the continuous development of corrosion until macroscopic failure. The results above provide reference opinions for strengthening anti-corrosion in storage.
