Patent number: 10843571Abstract: 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.Type: GrantFiled: July 18, 2018Date of Patent: November 24, 2020Assignee: ARMY ACADEMY OF ARMORED FORCESInventors: Guozheng Ma, Haidou Wang, Yiwen Wang, Pengfei He, Shuying Chen, Ming Liu, Zhiguo Xing, Haijun Wang, Binshi Xu

Patent number: 10752983Abstract: Provided are a system and process for remanufacturing a waste cylinder assembly of an aircraft piston engine. The spraying apparatus includes a first power mechanism, a spray gun assembly and a second power mechanism. The first power mechanism drives the cylinder assembly to move in a horizontal direction and a vertical direction. The second power mechanism drives the spray gun assembly to rotate around a center of the blind hole and ensures that prepared coatings can be evenly distributed along an inner wall of the blind hole. A nozzle end of the spray gun extends into the blind hole, and the spray gun is adjustable relative to the center of the blind hole. A spraying distance is not fixed so as to change the spraying distance. Powder can be fully melted.Type: GrantFiled: July 18, 2018Date of Patent: August 25, 2020Assignee: Army Academy of Armored ForcesInventors: Haidou Wang, Guozheng Ma, Pengfei He, Shuying Chen, Fajun Ding, Yiwen Wang, Ming Liu, Haijun Wang, Shuyu Ding
