摘要: 采用加速腐蚀试验方法，研究了环境腐蚀和盐雾对LY12CZ铝合金板材的3种螺接型式、12种防护处理的典型螺接搭接件疲劳性能的影响，提出了几种较适用的螺接结构细节防护方法。结果表明，环境严重降低螺接件的疲劳性能。采用适当的细节防护措施，可提高结构的抗环境损伤性能，疲劳性能一秀有不同程度提高。其中，采用3号船用润滑脂安装和底漆湿装配是比较有效的方法，与未经防护处理的试验件相比，其在试验环境中的疲劳寿命分别提高78.36%和83.45%,DFR值分别提高15.09%和15.88%。

Abstract：The effect of environment corrosion and salt fog on fatigue properties of 3 types of bolted joint structures and 12 kinds of protective measures of LY12CZ Al- alloy plate typical bolted lap joints was studied by an accelerated corrosion test. Several protective measures for detail structure improving properties of LY12CZ Al-alloy bolted structure against environment corrosion damage were presented. the results showed that environmental corrosion worsened the fatigue properties of the bolted joint structures. The anti-corrosion damage and fatigue properties of bolted joints can be generally increased to different degree if appropriate protective measures were applied to the detail structure of bolted joints. installed bolt with marine grease and wet installed bolt with primer studied in the paper were more effective to improve anti-environment damage properties of the bolted joints. Their fatigue properties were increased obviously compared with those not treated in the testing environment. Their fatigue life were increased by 78.36% and 83.45% respectively, and their DFR value were increased by 15.09% and 15.88% respectively.

Key words： corrosion environment bolted lap joint corrosion damage protective measures fatigue property Al-allo
