Study on the Application of Thermal Spraying Technology for Bogie Frame

Bogie is the running part of rail vehicles and is one of the core components of rail vehicles. The frame, as the skeleton of the bogie, is the key load-bearing part of the bogie and the basis for the installation of other components, which connects the components of the bogie and transmits the forces in all directions. At present, the frame is welded with carbon steel plate. In the frame design of some vehicles, the bogie chamber is used as an additional air chamber, which is connected with the air spring to ensure the comfort of the vehicle. Due to the influence of external origin, with the passage of operating time, the structure cavity will appear rust phenomenon. In this paper, based on the frame manufacturing process, the method and parameters of thermal spraying technology for
