As a method for detecting the rail defects, the nondestructive ultrasonic testing technique has been used. Since the ultrasonic transducer should be direct contacted to the surface of rail, damage and failure of the ultrasonic transducer are occurring due to its wear from the rail. This study was conducted to develop the wear-resistant material of ultrasonic transducer for inspecting the rail. The PMMA (Poly(methyl methacrylate))-based wear-resistant materials were fabricated by polymerization method. Various additives to PMMA were used. Four kinds of PMMA-based wear-resistant materials were fabricated and their characteristics such as abrasion, impact and ultrasound were measured and compared. Finally, as an wear-resistant material of ultrasonic transducer for inspecting the rail defect, the material of which Taber abraion and Izod impact energy were 165 mg loss and 2.35 kJ/m2 Izod was selected.
