The present disclosure relates to a novel high-performance repairable sliding plate of a pantograph of an electric locomotive and a manufacturing method thereof. The sliding plate includes a monometallic substrate and a conductive, wear-resistant, anticorrosion and self-lubricating coating integrated with the substrate. The coating is formed by plasma spraying Cu—TiO2 core-shell composite powder on the monometallic substrate directly, and includes the following components by mass percent: 60-70% of Ti4O7, 15-25% of Cu, 10-15% of TixO(2x−1) and 5-10% of TiO2, where 5≤x≤10. The multifunctional composite coating is the working layer of the sliding plate of the present disclosure, and the damage of the coating can be repaired by plasma spraying with the composite powder, thereby recovering dimensional accuracy and service performance.
