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。
In this paper, the effects of temperature, pH value and pre-etching time on the corrosion fatigue (CF) properties of LY12CZ coated aluminum alloy riveted joints in 3.5% Nacl solution were investigated under stress control. The results show that the increase Temperature, lower PH value and prolonged pre-corrosion time, will reduce the corrosion fatigue life of the connector.
