The article presents studies whose aim is to use such technologies of improving surface layer of a wheel seat that would eliminate fretting wear. The studies were carried out on a simplified physical model of an actual connection between the wheel and the axle of a wheel set with a self-acting wheel track change. The results of carried out wear studies show that fretting wear development can be successfully limited when metallic coating in the form of molybdenizing is used. Carried out studies indicate that such a solution can be fully used in actual exploitation.
