摘　　要：采用有限元法对高强结合性能涂层与基体界面结合强度进行了力学模拟,通过对涂层与基体界面最大法向应力和最大剪切应力的分析,比较了模型中有无金属加强板,不同的锥度、结合面宽度、涂层厚度对界面结合强度的影响,从而确定了最佳模型,使模拟过程中最大剪切应力明显降低,能够更好地体现不同体系法向应力的变化,并在最佳模型下研究了不同涂层和基体材料相互作用的界面结合强度。Based on finite element method, it performs the mechanics evaluation of bonding strength between high-performance coating and substrate, proposes an improved test model to optimize its structure dimension. It analyzes the maximum tensile stress and the maximum shear stress on the coating and substrate interface, compares the influences of the metal strengthening slab of model and width of bonding- interface and thickness of coating on the interface bonding strength of coating - substrate. The results show that the model decreases obviously the maximum shear stress, changes the tensile stress in different systems.
