针对多件2Cr13不锈钢轴流压缩机叶片在交付时出现锈蚀的现象，采用宏观分析、金相检验、硬度测试以及扫描电镜与能谱分析等多种材料检测方法对叶片出现锈蚀的原因进行了分析。结果表明: 叶片锈蚀是因为其存在纵向贯穿性纯铁夹杂缺陷，在潮湿或腐蚀性环境作用下发生电偶腐蚀所致；该缺陷产生于冶炼过程中，采用无损检测方法难以检测出，可通过采用盐酸+氯化铁水溶液低倍腐蚀的方法及时发现缺陷，以避免造成更大损失。

Aiming at multiple axial flow compressor blades occurring rusting phenomenon upon delivery, material detection methods such as macro examination, metallographic examination, hardness test and scanning electronic microscope and energy spectrum analysis were used to analyze the rusting reasons of the blades. The results show the blades rusting was because there were longitudinal through and through pure iron inclusion defect in the blades, and the inclusions reduced in galvanic corrosion in wet or corrosive environment. The pure iron inclusion defect produced in smelting process, and it was difficult to be detected by non-destructive testing method. However, it could be found out in time by macroscopic corrosion examination method with hydrochloric acid and ferric chloride aqueous solution to avoid greater losses.
