Abstract: In the course of the fluorescent penetration inspection for engine turbine blade, appearance of over-fluorescence background will lead to the failure in fluorescence detection for blade. In this paper, the method of combining theory and process test is adopted to analyze the cause of over-fluorescence background, and an effective solution is worked out. Test showed that such solution could greatly improve performance of the fluorescence background for the high-pressure turbine blade.
