摘　　要：选用了LY12CZ铝合金和TA2钛合金两种基体,分别采用了两种不同的表面处理方法对其进行表面处理:砂纸打磨、磷酸阳极化(PAA)和砂纸打磨、阳极化(SHA);研究了不同表面处理方法对Al/Al环氧胶接接头、Ti/Ti环氧胶接接头老化性能的影响,结果表明,与砂纸打磨法相比PAA和SHA表面处理法能显著提高环氧胶接接头在介质中的老化性能,尤其是在低温介质中的耐久性.The effect of surface pretreatments of bonding metal on the bond strength of the bonded joint with epoxy glue was studied in this paper. Two kinds of metal bonded joints were used in this experiment： one was aluminum alloy, and the other was titanium alloy. The sand paper polishing and phosphoric acid anodic oxide（PAA） , and the sand paper polishing and sodium hydroxide（SHA） were used to polish aluminum alloy and titanium alloy, respectively. The results show that both of PAA and SHA can enhance durability of Al/Al and Ti/Ti epoxy bonded joint in media in comparison with sand paper polishing.
