英文摘要	During the service of the tritium barrier coating, the cracking behavior and the roughness of substrate are important in the fusion reactor. In this study, the extended finite element method (XFEM) is utilized to investigate the relationship between substrate surface roughness and crack behavior in tritium barrier coating system, which consists of Al2O3 coating and 316 L stainless-steel substrate. The results demonstrate that the roughness of the substrate surface affected the strain energy release rate and the propagation patterns. The driving force of crack exhibits different distribution in the peak and valley regions of the substrate surface. The stress, along the path of the rough interface, can be partially suppressed. Moreover, the multiple cracks significantly reduce the growth of cracks.
