Abstract According to dynamics of coupled sacrificial anode with carbon steel,the integral of galvanic current vs.time approximately equal to actual current capacity of sacrificial anode.Galvanic current of cast aluminum alloy sacrificial anode coupled with carbon steel are tested,as-cast surface,in 3%NaCl sol
ution,ambient temperature.Evaluation of the performance of sacrificial anode of as-cast surface rapidly using galvanic current is feasible, that can be used to get the best sacrificial anode among a series anodes of same group according to orthogonal design,the test period can be 20 minutes.
