英文摘要:
      In this paper, aluminum bronze polyester wear-resistant coating was prepared on the support ring of typical parts by atmospheric plasma spraying process. The hardness, bonding strength, microstructure and other properties of the coating were tested. The wear-resistant performance of the whole support ring coating machine after bench test under the conditions of 20000 r/min rotating speed, 800 N·m input torque, 90~100 ℃ lubricating oil temperature, 0.2~0.3 MPa lubricating oil pressure, and 50 h operation time was mainly examined. The test results showed that the prepared uniform aluminum bronze polyester wear-resistant coating exhibited the hardness of 89.6 HR15Y, the bonding strength of 25.5 MPa with porosity of 15.18%. The appearance status of the typical component coating after bench testing was checked using visual and stereomicroscopes, and the wear amount of the coating was calculated by high-precision three-dimensional measurement methods. The bench testing results showed that the aluminum bronze polyester coating of the typical component was complete, smooth, and free from cracking, peeling, the wear amount at the most severely worn position of the coating was 0.006 mm, indicating excellent wear resistance of the coating.
