采用金相（ＯＭ）、俄歇（ＡＥＳ）、扫描电镜（ＳＥＭ）及透射电镜（ＴＥＭ）等技 术手段对实海暴露试样进行探测分析，揭示了表面膜缺陷（如碳膜）、晶界缺陷（晶界析出物）等加速该 合金腐蚀进程的试验现象和内在根据，特别指出影响该合金海水腐蚀产物膜稳定性的主要因素，分析了其中的沿晶扩散及应变诱生调峰分解与沿晶腐蚀、沿晶脆断的相互关系。
The metastable pitting behaviors are closely related to stable pitting process and have been paid special attention by many researchers. Recent progress on experimental methods for metastable pitting study, the statistical principles and mechanisms of nucleation and growth of metastable pits, and the transition condition from metastable pits to stable pits are reviewed. Futher study is envisaged.
