英文摘要： Glass-metal hybrid structures have advantages of high structural strength, leak-tightness and thermal insulation. It not only holds superiority of energy-saving and environmental protection, but also represents the design aesthetics of automobile, modern architecture and transportation conveyance. The key for the wide application of this hybrid structures is reliable bonding of glass to metal and its safety. The projects aimes to bond glass blocks to metal. Based on the coupled effect of high-energy beam texturing and ultrasonic cavitation, A new method of laser induced fusion bonding of glass to metal with ultrasonic-assisted was proposed. The research starts from studying the high-energy beam texturing of metal surface and the wetting behavior of melting glass on textured metal surface. Using textured bulges as micro channels of ultrasonic cavitation, the non-equilibrium wetting in glass-metal interface induced by ultrasonic and the kinetics mechanism was studied. The effect of temperature field on the formation and evolution of solid-liquid-solid phase in interface area was investigated using in-situ measurement of heating temperature and microstructure analysis. The possible chemical reaction of interface and the therodynamic was studied using therodynamic calculations and microstructure analysis. In additi
