    On Wheel-rail Contact Surface Phenomena with Structural Changes and ˇWhite Etching LayerˇGeneration

  • Original language description

    The main aim of this work was a study of the microstructure transformations with the residual stress formation that is induced by rolling contact friction and (adhesive) wear in the rail - wheel system. Several small rail-surface samples, we term them asthe "chips", and a piece of wheel sample were chosen for an analyses of the surface changes on the rail/wheel surface. A multitude of different experiments were carried out in order to analyse the microstructure changes at the surface and the near-surface region of the material samples and, thus, to contribute to the understanding of the complex rail/wheel rolling contact phenomena - and its degradation mechanisms. The formation of nano-structured martensite and carbides on the rail and wheel surface causes the extremely high microhardness values and the strong corrosion resistance of the so called White Etching Layers (WEL).
