contactThe crossing of the electric current in rail lines through a copper/QCr0.5 sliding contact worked nakedly in ambient environment and its tribological properties were influenced by atmospheric conditions, such as weather variations of rain or snow. The influence of water on the tribological behavior is made in evidence and analyzed.
