| 中文摘要: |
| 通过模拟海水/海洋大气干湿交替环境,研究了四种典型牺牲阳极的工作电位变化规律、电流变化规律、溶解产物形貌及产物成分。结果表明:在干湿交替环境中,四种牺牲阳极的性能由好至差依次为Al-Zn-In-Mg-Ga-Mn阳极、Al-Zn-In-Mg-Ti阳极、Al-Zn-In-Cd阳极、Zn-Al-Cd阳极,合适成分的Al-Zn-In-Mg-Ga-Mn阳极是用于干湿交替环境下较为理想的阳极材料。 |
| 英文摘要: |
| The change regulations of working potentials, electric currents, morphology and compositions of dissolved products for four typical sacrificial anodes were investigated in simulated seawater and simulated marine atmospheric environment for wet-dry cycles. The results showed that the performance of the four anodes under wet-dry cyclic environment decreased in the following order: Al-Zn-In-Mg-Ga-Mn anode,Al-Zn-In-Mg-Ti anode,Al-Zn-In-Cd anode,Zn-Al-Cd anode. Hence Al-Zn-In-Mg-Ga-Mn alloy with appropriate composition was an ideal anode material under wet-dry cyclic environment. |
