Optimization of Sacrificial Anodes in Slop Retention Tanks of Ship

Since the catrhodic protection requirments in design can not be met for the anti-corrosion of ship bottom tank due to the premature failure of the zinc-aluminium-cadium sacrificial anode with crust covering the anodes in the water envirioment contaminated by oil,electrochemical performance of anodes was tested in the water simulating to real ship bottom environment and a kind of aluminium alloy sacrificial was developed with high efficiency and tolerance to oil contamination water.
