RESEARCH ON WEAR-RESISTANT MATERIALS FOR RAILWAY ROLLING STOCK WHEELS

WERKSTOFFENTWICKLUNG FUER VERSCHLEISSAERMERE EISENBAHNRAEDER

A study of work-hardened running surfaces of wheels, carried out with an electron microscope, has shown that the formation of carburized particles was a significant factor in wear. The rolling movement in contact with the rail destroys the flakes of cementite, and particles are detached from the texture of the metal. At the same time, flakes of ferrite, which are soft originally, are cold-hardened by the running movement, and cause cracks. The article reports on research to improve resistance to wear and thermal shock in steels used for making wheels.
