摘要: 对IC10单晶高温合金导向叶片荧光渗透检测的缺陷荧光显示进行了分析，确定了缺陷性质主要为显微疏松缺陷；通过对比试验获取了航空发动机涡轮叶片常用的渗透检测灵敏度等级和方法的特点和区别。试验结果表明：采用后乳化荧光渗透检测法对IC10单晶高温合金导向叶片缺陷的检出更为合适。

Abstract: The defects indications are analysed for IC10 single crystal blades inspected by FPI method. The defects indications are mainly microporosity defects, the FPI sensitivity class and the character and difference of method are got by FPI contrast testing. It is indicated that the Post emulsification fluorescence penetrant inspecting method is fit for defect inspection.
