Influence of Current on Wear Modes and Transition Condition of Current Collecting Materials

It is necessary to understand actual phenomena generated at the electric contacts to suggest the design concept for reducing wear of current collectors such as a contact wire and contact strip in an electric railway. However, rotating wear testing method like pin-on-disk which commonly used to evalu...
