Abstract
A bogie shaft for railway vehicles has a cladding which contains a metal component. The metal component is preferably electrochemically less refined, but no greater than exactly as refined, as a material of the bogie shaft. Corrosion on the bogie shaft can thereby be advantageously prevented. The metal material of the cladding is also able to effectively protect the bogie shaft against stone impact. The cladding can be advantageously applied by cold gas spraying, or a sleeve can be bent around the bogie shaft for forming the cladding. The cladding can advantageously contain particles that can make it more resistant to stone impact. The particles can be made, for example, of hard materials, of particularly ductile particles, or of particles made of a memory shape alloy.
