Abstract.
Sacrificial anode cathodic protection is one of the most widely used methods in protecting
buried oil pipe lines against the corrosion damages. In the present work, a series of Aluminum alloys
have been prepared as sacrificial anodes candidates to be used in the protection of the oil pipelines
that pass through the Al-Hilla region. These prepared alloys were microstructurally and
electrochemically characterized to evaluate their performance as Al-sacrificial anodes for cathodic
protection of oil pipes The relationships between the protection potential with time, sacrificial anode
life, discharge currents, and capacity of sacrificial anodes were found, taking into consideration the
distance between sacrificial anode and protected steel sample. According to the results obtained, the
best selection of sacrificial anodes was (Al-4% Zn-0.5% Sn) alloy at 30cm in Al-Hilla region.
