为研究碳钢点蚀声发射信号特征，对6%氯化铁溶液中碳钢点蚀过程进行了声发射监测。采用K-均值方法对信号进行了聚类分析，通过分析各类信号持续时间、计数、幅度等特征，识别了碳钢点蚀过程中不同声发射源。结果表明碳钢在氯化铁溶液中的点蚀声发射信号可通过聚类分析方法区分和识别不同声发射源信号。
為研究碳鋼點蝕聲髮射信號特徵，對6%氯化鐵溶液中碳鋼點蝕過程進行瞭聲髮射鑑測。採用K-均值方法對信號進行瞭聚類分析，通過分析各類信號持續時間、計數、幅度等特徵，識彆瞭碳鋼點蝕過程中不同聲髮射源。結果錶明碳鋼在氯化鐵溶液中的點蝕聲髮射信號可通過聚類分析方法區分和識彆不同聲髮射源信號。

In order to study acoustic emission (AE) signals characteristics of pitting corrosion on carbon steel, Pitting corrosionprocessoncarbon steel in 6%ferric chloride solutionwas monitored by AE technology.K-mean cluster algorithm was used to classify the monitored AE signals, in which the duration, counts, amplitude, absolute energy and peak frequency were analyzed as the AE signals characteristics, and different types AE sources were identified. The results showed that there were mainly four type AE sources during carbon steel pitting corrosion process in ferric chloride solution, and the different types AE sources signals could be classified by cluster analysis.
