| Abstract: |
| Metal-matrix ceramic coating can be prepared on the surface of TBM (Tunnel Boring Machine) cutter ring by laser cladding technology to improve the wear resistance, but the residual stress distribution of cutter ring significantly changes in the preparing process. The unreasonable distribution of residual stress of coating may cause low cycle fatigue fracture of cutter ring in service. In this study, the influence of scanning path on stress distribution and maximum/ minimum value of stress is studied during the process of coating preparation to decrease the failure risk of TBM coated cutter ring, which will provide theoretical guidance for optimizing the residual stress distribution of coated cutter ring. |
