| Abstract | This paper applies bullet to induce shock wave and detects the adhesion behavior of multiple interfaces in typical thermal barrier coating system. Post-shock metallography examination is carried out to show the real characteristic of interface delamination. A finite element-based acoustic wave mechanics simulation is conducted to calculate the stress history. It is found that delamination can occur in every interface, depending on bullet velocity and stress feature. An interesting phenomenon of the failure at multiple interfaces during a single shot needs to be paid more attention in the future. |
