Article Preview

In the present paper, the induced current focusing potential drop (ICFPD) technique is applied to the detection of surface and internal defects for railway wheels. To detect the defects for railway wheels, the sensors for ICFPD are optimized and the tests are carried out with respect to 4 surface defects and 3 internal defects each other. The results show that the surface defect of 0.5 mm and internal crack of 1.0 mm apart from surface of wheel tread could be detected by using this method. The ICFPD method is useful to detect the defect that initiated in the tread of railway wheels.
