摘要
在 2 0℃和 6 5℃ ,对Al Zn In Sn Mg牺牲阳极进行电化学性能测试、活性离子沉积实验、极化腐蚀形貌观察和孔蚀性能的测定 .分析认为 :在常温下 ,铝阳极的活化过程主要是活性元素的“溶解 再沉积”过程 ;
Aiming at AL-Zn-In-Mg sacrificial anodes, an inves ti gation of the electrochemical performance, deposition behavior of active element s, corrosion characteristic and pit corrosion performance were made at 20°C and 65?℃. The results showed that the dominative course of aluminum anodes dissol ution was the deposition of active elements at the ambient temperature and pit c orrosion and intercrystalline corrosion at the elevated temperature.
