摘　　要：According to dynamics of coupled galvanic anode with carbon steel,the integral of galvanic current vs.time is approximately equal to actual current capacity of galvanic anode.Galvanic current of cast aluminum galvanic anode coupled with carbon steel is tested in3.5%NaCl solution and ambient temperature.Rapid evaluation the performance of galvanic anode using galvanic current is feasible,and the test time is20min.The galvanic current is used to select aluminum galvanic anodes in oil brine,and then test the galvanic anodes with impressed current test method.The result shows,the performance of galvanic anodes degrads in oil brine,but has not much difference in the two media to the preferable anodes,and the optimal galvanic anode is gained.
