Fretting is manifested by the occurrence of wear debris from surface cracks [5][6][7]. The debris falls out from the pressed joint and the fretting process as well as the products of fretting is very similar to the corrosion process.…”

This paper deals with the influence of adhesive on the pull-off test for the molybdenum layer of the railway wheel set axle. Certain axle types are fitted with a Mo coat used to provide protection against fretting and external influences. Pressing is used for the wheel-axle assembly procedure. During the process of pressing, this surface layer is damaged, which results in a corrosive tendency in the pressed joint. That is why great emphasis must be put on the Mo layer quality and its parameters must be tested in a suitable manner. Testing means identification of the surface tensile strength. The pull-off test provides a good tool to resolve the present problem. K e y w o r d s : pull-off test, Mo-coatings, railway axles, material behaviour, fretting
