Abstract
The electrochemical impedance spectroscope(EIS) of 907A steel in seawater was investigated to study the film formation and destruction. The corrosion protection mechanism of the synergy interaction between cathodic protection and YKI_5 corrosion inhibitor(a mixture of polyhydric alcohol phosphate ester, phosphate and polyphosphate) is discused. Typical EIS spectral changes were clearly observed during the film formation and destruction processes. EIS results indicated that the film seemed to formed a multi_layered structure which consist of an inner layer(this may be an inhibitor_metal complex layer) and many outer layers of calcareous deposits. The film possesses of good persistency under the testing conditions.
