Abstract

The invention relates to a high-performance self-lubricating copper-based pantograph pan material and a preparation method thereof, and belongs to the technical field of high-speed carrying equipmentdevelopment. The self-lubricating copper-based pantograph pan material is prepared from, by mass, 40-70 parts of copper-tin alloy powder, 10-30 parts of pure copper powder, 4-12 parts of iron-copper alloy powder, 2-6 parts of copper-chromium alloy powder, 5-9 parts of lead powder, 1-4 parts of graphite powder and 1-3 parts of molybdenum disulfide. According to the preparation method, the copper-tin alloy powder, the iron-copper alloy powder and the copper-chromium alloy powder are adopted to replace elemental tin powder, iron powder, chromium powder and the like to serve as a reinforcing phase, the sintering temperature can be effectively reduced, and the problem of loss of the low-melting-point elemental tin powder in the sintering process is avoided. Through reinforcement, the high-temperature stability and anti-ablation capability of a copper matrix are improved, the deformation and adhesion of a pan in a high-temperature environment caused by friction are suppressed, the loss of the pan is reduced, and the friction resistance of the pan is improved.

Description

technical field [0001] The invention relates to a high-performance self-lubricating copper-based pantograph sliding plate material and a preparation method thereof; it belongs to the technical field of high-speed carrying equipment development. Background technique [0002] The pantograph slide is an integral part of the pantograph, which is fixed on the top of the bow head through conductive glue or mechanical locks, and is in direct contact with the catenary wire. During the operation of the electric locomotive, the pantograph sliding plate slides on the catenary wire and obtains current from the wire to provide power for the locomotive. It is an important current-collecting component of the power source of the electric locomotive. The pantograph slide must meet various performances at the same time: (1) good mechanical properties such as surface hardness, tensile strength and impact toughness, to ensure that it will not be damaged during use; (2) good wear resistance, to ...
