针对激光冲击强化应用技术中的自由约束层厚度的问题 ,分析了涂层气化、爆炸形成的向金属层内部和自由约束层内部传播的高强度压力、自由约束层与涂层之间的粘着力和约束层本身性能之间的关系。推导了自由约束层的最佳理论厚度———既能获得最佳冲击强化效果 ,又可达到一次高效安全地清除自由约束层的目的
Aiming at the problem of the free constrained layer thickness in the application of laser shock enhancement technology, the high-intensity pressure propagated inside the metal layer and the free constrained layer formed by gasification and explosion of the coating was analyzed. The adhesion between the free constrained layer and the coating The relationship between forces and constraints themselves. The optimal theoretical thickness of the freely constrained layer is derived - both for optimum impact enhancement and for the purpose of efficient and safe removal of the free constrained layer
