Application of Fluorescent Magnetic Powder Non-destructive Crack Detection in Ship Inspection

In this paper, the characteristics and the theoretic fundamentals of fluorescent magnetic powder non destructive erack detection method are introduced. The equipments and materials, the operation and protection problems are described. Comparing this method with the common magnetic powder method, it proves that the sensitivity of the former is higher than the latter in the crack detection. The effectiveness of this method is in the ship inspection is confirmed by the practical instances.
