摘要
本文在应力控制下分别研究了温度、ｐＨ值和预腐蚀时间对ＬＹ１２ＣＺ铝合金带有涂层的铆接连接件在３．５％Ｎａｃｌ溶液中腐蚀疲劳（ＣＦ）性能的影响规律，结果表明；提高温度，降低ＰＨ值和延长预腐蚀时间，均会缩短连接件的腐蚀疲劳寿命。
The effect of temperature, pH value and pre - immersion duration on the behavior of corrosion fatigne(CF) for LY12CZ aluminum alloy riveted lap - splice joints with coating were studied in 3. 5 % NaCl solution Under load control condition. The results showed that higher tempeoature, lower pH value and longer pre - imnsersion would decrease the CF life of the riveted specimen
