异种金属接触因电位差而产生腐蚀问题。接触腐蚀导致结构的强度损失和腐蚀增重。复合材料飞机垂尾、襟翼、副翼与铝合金或钢机身或机翼连接常用钛合金螺栓。因而,要研究减少和避免钛合金紧固件接触腐蚀的电化学机制。 1.实验结果 实验采用的电解液为自然状态的5％NaCl溶液,电解池中参比电极是饱 Dissimilar metal contact due to potential corrosion problems. Contact corrosion leads to structural loss of strength and corrosion gain. Composite aircraft vertical tail, flaps, aileron and aluminum alloy or steel fuselage or wing commonly used titanium alloy bolts. Therefore, to study to reduce and avoid contact corrosion of titanium alloy fasteners electrochemical mechanism. 1. Experimental Results The electrolyte used in the experiment was a 5% NaCl solution in a natural state. The reference electrode in the electrolytic cell was full
