Investigation of the Influence of Surface Strengthening Technology on the Material of Railway Car Wheel Axles

Abstract:

Article Preview

Surface rolling is a cold-working technology for hardening the surface of components made from steel or ductile cast iron. This process is able to increase the hardness of surfaces and to improve fatigue properties, so it is usually used on axles (shafts) of railway car wheels. In this paper the influence of surface strengthening technology on the microstructure of the material of railway car wheel axles is studied by micro hardness tests, optical microscopy, scanning electron microscopy (SEM) and X-ray line profile analysis.
