Wear Resistance of Rails

Resumo

The operational wear of rails is analyzed and the actual wear is determined in measurements within the OAO RZhD network and in the laboratory. The wear resistance of rail steel is investigated as a function of the chemical composition and the microstructure (specifically, the dispersity). The microstructure of rail steel with different wear resistance is investigated by means of an electron microscope. Metallurgical approaches to improving the wear resistance of steel are described. Operational measures are also noted.
