The trend to use modern materials and technologies in the development and construction of rail vehicles leads to testing new suitable alternatives for surface treatment of strain parts. Within the research project, suitable thermally sprayed coatings as alternatives for former surface treatment of selected components of rail vehicles are tested. The aim is to increase the functionality and service life of these parts. One of the key properties of these coatings has to be resistance against corrosion in the salt environment, as they need to protect the part for the whole life span in climatic conditions. In this study, possible coatings and the technology of their application are chosen for two components. These components are treated and tested in salt fog for 1000 hours along with parts treated by conventional surface treatment. The potential of the coatings for protecting the parts is analyzed. Based on the results, a suitable coating for the component will be selected.
