| 摘 要： | 研究了三种Al-Zn-In牺牲阳极在低温下的电化学性能，其中Al-Zn-In-Cd牺牲阳极在低温时电流效率为84%左右，阳极溶解呈非均匀状，腐蚀产物不脱落，不适用于低温环境；Al-Zn-In-Mg-Ti牺牲阳极在低温时电流效率为90%左右，表面呈均匀状溶解，腐蚀产物脱落，具有较好的电化学性能. |
| 关 键 词： | 电化学性能 牺牲阳极 低温 |

| Abstract: | The electrochemical behavior of three kinds of Al-Zn-In sacrificial anode at low temperature was investigated.The current efficiency of Al-Zn-In-Cd anode at low temperature was about 84%,the surface dissolution of which was non-uniform,and the corrosion product adhered on the anode,thus this sacrificial anode was not suitable for low temperature environment.Whilst the current efficiency of Al-Zn-In-Mg-Ti sacrificial anode is about 90%,the surface dissolution of which was uniform,and the corrosion product fe... |
