Magnetic flux leakage testing (MFL) is used extensively for the nondestructive inspection of steel wire ropes. Corrosion detection has always been difficult in wire rope testing. Corrosion damage is a type of irregular geometry that can exist anywhere, and its morphology is often within a certain range of scale with statistical self-similarity. By analyzing the fractal characteristics of the magnetic leakage signal obtained from corroded steel wire rope, a quantitative calculation of the fractal dimension for MFL of steel wire rope is proposed. The results show that the technique can calculate the corrosion degree of steel wire rope by simulation. The technique is unaffected by unfavorable factors during testing. The authors tested steel wire rope with different degrees of corrosion using the technique. The experiment proves that the technique can determine the degree of corrosion and circumferential position of the steel wire rope accurately.
