Abstract: Switch slide base plate was one of the important components of rail transit lines, and its normal operation was the basic guarantee for the safety of train operation.At present, Q235 steel was used for slide plate in China, which needs to be oiled and maintained manually and periodically.This method is obviously influenced by service environment, huge cost and potential hazards such as environmental pollution and operation safety.Self-lubricating copper matrix composite with good wear and corrosion resistance was used to strengthen the surface.The situation and cladding properties of the sample prepared by pre-set process were compared.Finally, the suitable preset process and corresponding process parameters were obtained.
