In view of existing problems of current electric locomotive pantograph slide plate, a new pantograph slide plate was developed using powder metallurgy technology. The new pantograph slide plate consisted of copper, carbon fiber, graphite, etc., and the influences of pressure and sintering temperature on the performance of pantograph slide plate were evaluated based on the measurements of friction, abrasion and impact toughness of test samples. Performance of these pantograph slide plates was compared with other brands that are being used now. The results showed that the best plate was prepared with the conditions of the composition of copper 78 %, carbon fiber 2 %, graphite 15 % and additive 5 %, pressure 200 MPa and sintering temperature 880 deg C. Its performance in friction, abrasion and impact toughness, etc., was improved compared with current carbon slide plates: friction coefficient was reduced by 54.5 %, abrasion rate decreased by 41 %, impact toughness increased by 9.6 times and conductance increased by 8 7 times.
