摘　　要：本文从环境暴露时腐蚀介质的传输规律研究、环境暴露对汽车车身金属胶接接头力学性能影响及其降级机理、金属被粘物表面处理技术几个方面对其胶接接头腐蚀方面的研究现状进行了综述,并探讨了金属胶接接头环境抗腐蚀性能研究的发展趋势,认为腐蚀介质在胶接接头界面的扩散规律、接头金属表面的电化学反应破坏其界面结合性能的机理及规律、金属接头中的电化学腐蚀规律及电化学反应对黏合性能和接头强度影响等方面是今后的主要研究重点。Research status on the environmental corrosion resistance of adhesive bonding automotive body metal joint was summarized from the transfer law of corrosive medium when expose to environ- ment, effect of environmental exposure on mechanical properties of adhesive bonding metal joint , the degradation mechanism and surface treatment technology of metal adherend. The developing trend of the study on the environmental corrosion resistance of metal bonding joint was discussed. The results show that the further research should focus on the diffusion law of corrosive medium in the interface of the adhesive bonding joint, the mechanism and law of the damage of electrochemical reaction on metal joint surface to the interface bonding performance, the electrochemical corrosion law in metal joint, and the effect of electrochemical reaction on bonding performance and the strength of joint.
