摘要

Abstract

The Al—basic sacrificial anode is widely used to protect steel construction from corrosion in seawater

but is not suitable for protecting steel in freshwater. In the estuary area

seawater and freshwater mix and different seawater salinity can be formed in different mixing sites between freshwater and seawater. Based on the requirements of the Shengli Petroleum Administrative Bureau of China

the effect of seawater salinity on electrochemical properties of Al—basic anode was studied under laboratory conditions by the method given in National Standard GB 4948-85 (China Starndard Bureau

1985). No obvious effect was found when seawater salinity was 30 to 10

but obvious effect on anodic open circuit potential

closed circuit potential and current efficiency was found when seawater salinity was 5. These values are lower than those given in the National Standard.
