| Abstract: |
| In this paper, the research progress of erosion resistant coatings on blade tip in recent years is reviewed from four aspects:tip working condition and damage mechanism, coating structure, research status and deposition method. Firstly, the actual working conditions of compressor blade tip and sand erosion damage mechanism are introduced, such as micro cutting theory for low incidence angle and secondary erosion theory for high incidence angle. Secondly, the material and structure design of erosion resistant coatings and the matching problem of hardness and toughness are emphasized. The microstructure of nano multilayer, nano composite and single-phase solid solution structure are expounded in detail. The extrinsic hardening and toughening mechanism and structural design criteria are summarized in detail. Then, the latest research progress in the field of erosion resistance is introduced. Finally, the characteristics of four international mainstream ion beam deposition techniques in microstructure design and composition control are compared to find that the filter cathodic vacuum arc technique has irreplaceable advantages in the preparation of deposition of erosion resistant coatings on blade tip. In order to optimize the coating performance and promote practical application, the application prospect and industrial production of erosion resistance coatings prepared by filter cathode vacuum arc technique are prospected, providing references for the popularization of FCVA in the field of tip protection. |
