れていた。However, in recent years, the speeding up of electric vehicles has been remarkable, and along with this, the pantograph 1
Since the current collection per unit increases, the wear of the contact plate tends to increase remarkably. In addition, the number of pantographs tends to be reduced in order to prevent an increase in noise due to the increase in speed, and this also causes an increase in the abrasion of the contact plate along with an increase in the current collecting current. Furthermore, the increase of the current collection increases the Joule heat due to the contact resistance between the contact plate and the trolley wire, which may cause heating and fusing of the trolley wire.
There has been a demand for a pantograph siding plate material having wear resistance far superior to that of a conventional pantograph siding plate material and having a low resistivity.

Using the device installed eccentrically to the hard copper ring,
While pressing the ground plate material at two places on the diameter line with a pressing force of 55 N to bring the dimension surfaces of length: 80 mm x width: 25 mm into surface contact, 100 V and 10 V are applied between the simulated trolley wire and the ground plate material.
A direct current of 0 A is applied and the disk is heated to 270 k in 5.5 minutes.
The rotation speed was increased to m / h, the speed was kept at this speed for 5.5 minutes, and then stopped for 5.5 minutes. This cycle was defined as one cycle, and this cycle was repeated 4 times. Also, the wear depth of the simulated trolley wire as the mating material was measured. From these measurement results, the specific wear amount of the contact plate material and the value per 5000 revolutions of the simulated trolley wire were calculated, and are shown in Tables 3 and 4.
