| Abstract: |
| 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. |
