| 摘 要： | 通过测定表面防护处理前后,Ti8LC钛合金、7710铝合金、ZL59铝合金、30CrMnSiA高强钢的电极电位,以及Ti8LC钛合金与其余3种材料组成偶对后的电偶腐蚀电流-时间曲线,研究了表面防护处理前后3种偶对的电偶腐蚀行为,并评估了电偶腐蚀敏感性.研究结果表明:Ti8LC与7710铝合金、ZL59铝合金、30CrMnSiA钢偶接时,会产生严重的电偶腐蚀,必须进行表面防护处理才能使用;采用涂层前处理+有机涂层防护的方法,可有效阻止Ti8LC钛合金与铝合金和高强钢的电偶腐蚀.

| Abstract: | Galvanic corrosion of Ti8LC titanium alloy coupled with 7710, ZL59 aluminum alloys and 30CrMnSiA high strength steel was studied through measurement of open circuit potential and galvanic current. Galvanic corrosion behavior of the three couples was studied before and after protecting treatment and their galvanic corrosion sensitivity was evaluated. The results show that when Ti8LC titanium alloy couples with 7710 aluminum alloy,ZL59 aluminum alloy, 30CrMnSiA high strength steel, there is serious galvanic corrosion, so the alloy must be suface protecting treated befor use; Surface treatment and organic coating can prevent the galvanic corrosion of titanium alloy coupled with aluminum alloys and high strength steel. |
