SOME EXPERIENCES OF WEAR, CORROSION AND CRACKING IN WHEELSET COMPONENTS OF A RAPID TRANSIT RAILWAY SYSTEM
While fretting corrosion and wheelseat cracking of axles have been overcome, deep fatigue cracks could form in axle bodies under exceptional circumstances. Ultrasonic testing must include the entire axle length. Quenching of an axle may extend the endurance of an axle containing a crack or other defect in the body and seems worthy of further investigation. London Transport's tests of various compositions and heat treatments of wheels and tires have shown nothing likely to eliminate formation of thermal cracks, although rim quenching shows some promise. Various factors in tread and flange wear are also discussed.
