objective Based on electrochemical noise technology, corrosion behavior Monitoring system of Q235 carbon steel is con Structed to monitor the corrosion process of Q235 carbon steel in the marine atmosphere. Methods the electrochemical noise data collected was analyzed by Time-domain spectrogram and frequency domain spectrogram. Results in the stage of 0.5 h-2.0 H (Sunny), the current noise amplitude was s Mall; The Time-domain spectra appeared a few transient peaks; White noise didn ' t appear on frequency spectra; The electrode was in passivation; From H to 47.5 h (rainy), the current fluctuated and the noise spectra appeared a large of transient; The slope of the PSD declined fast; The electrode surface was eroded; The electrode was in the steady pitting corrosion period. conclusion the monitoring system could continuously monitor corrosion Behaviors of Q235 carbon steel in the marine atmosphere.

With many advantages of light weight, high specific st^rength ,corrosion resistance ,easyprocessing , recyc^^ing and so on, the aluminum alloy is widely applied in the field of ocean. Under the atmospheric environment of the South Sea

and affected by its climatic characteristics, the corrosion types of aluminum alloy is in accordance with the EV Olution of pitting corrosion intergranular corrosion and exfoliation corrosion. Based on the study of corrosion mechanic and phenomena of aluminum alloy,thecorrosion ty PES and protective measures of aluminum alloys applied in the marine atmospheric-environment of the South Sea are Ed in this paper.
