Description of the Related Art Since a slider plate for a current collector slides in contact with a trolley wire, it is required to have excellent wear resistance, arc resistance, and current conductivity. Currently, contact plates made of copper-based or iron-based sintered alloys are widely used to meet these demands. The standard composition of a copper-based contact plate is 80-85% Cu, 9-12% Sn, F.

に対する追随性を高めることが困難であった。[0003]Requirements for slider plates have become more severe as the speed of vehicles has increased in recent years, and new emphasis has been placed on the ability to follow trolley wires. If the tracking ability of the trolley wire is insufficient, there is a problem that the wire will become detached more frequently during high-speed running, causing frequent arcing, which not only increases the wear and tear of the contact plate and the trolley wire, but also causes radio wave interference. . Since the slider plates currently in use are mainly composed of copper or iron, which has a high specific gravity, the slider plates themselves have a large mass, making it difficult to improve their ability to follow the trolley wire.

高めた後、円柱状にホットプレスした。Example 4 After stirring SiC whiskers and A6061 alloy powder in water to mix them uniformly, the water was evaporated and A6061 was mixed.
A mixed powder containing 20% by volume of SiC whiskers in the alloy powder was obtained. This mixed powder was filled into an aluminum can with an outer diameter of 170 mmφ, the inside of the can was evacuated through an exhaust pipe connected to the lid of the can, and the exhaust pipe was sealed by forge welding. This can filled with mixed powder was compressed at room temperature to increase the packing density, and then hot pressed into a cylindrical shape.

造することができた。The outer peripheral surface and both end surfaces of this hot-pressed material were cut to produce an extruded billet having an outer diameter of 150 mm and entirely made of composite material. This billet was extruded into a square bar shape, and the resulting square bar was cut into a forging material, which was then forged in a mold having a cavity of the same shape as the slide plate 1 shown in FIGS. 5 and 6. Thereafter, the forged product was subjected to T6 treatment, and the sliding surface was lightly cut and bored. This results in A6061 reinforced with 20% SiC whiskers.
It was possible to manufacture a slider plate made of an alloy and having the shape shown in FIGS. 5 and 6.

できた。Example 5 Si was added to the molten A4032 alloy heated to 750°C.
C whiskers were added little by little and stirred, resulting in a mixed molten metal in which 6% by volume of SiC whiskers were mixed and dispersed. This molten metal was poured into a mold having a cylindrical cavity and solidified to produce an extruded billet. This billet was subjected to the same post-processing as in Example 4. As a result, a slider plate having the shape shown in FIGS. 5 and 6 could be manufactured.
