| Abstract: | In compliance with the requirements of the Shengli Oil Field of Shandong, China, the effect of seawater salinity (30‐5) on the electrochemical properties of Al‐basis sacrificial anode was studied under laboratory conditions by the method given in the Chinese National Standard GB4948‐85 (Sacrificial Anode of Al–Zn–In System Alloy) 1]. The results showed that there was no obvious effect when the seawater salinity varied from 30 to 10, but that the anodic open circuit potential, closed circuit potential and current efficiency at seawater salinity of 5 were lower than those given in the Chinese National Standard. The variation of seawater salinity must be considered while designing marine projects in estuary areas. |
