A cell designed to produce an anaerobic experimental environment modeling sea bed sediments was used to test two kinds of steel(A3, and AP15LX) exposed to various Liaodong Bay sea bed sediment in 1988. The respective corrosion behaviour of coated, rusted and bare A3 steel surfaces in the same mud was investigated using potentiodynamic polarization method to obtain tlieir polarization curves under vari-ous corrosion environment determined.Potentiodynamic polarization experiments were conducted at scan rates of 5mV/s and one steel sample was polarized both anodically and cathodically in one measu-rement to avoid confusion caused by locally differing two sediment samples.The results show that this technique is sensitive to variations in surface corro-sion condition of the steel sample, types of sediments, temperature, resistivity of sediments etc.. The system can be used for comparison between different sediments corrosiveness and determining the corrosion behaviour difference of the same kinds of stee1 with various surface conditions and exposed to the same corrosion environ-ment. The authors suggest that this technique is useful for evaluating corrosiveness of sea bed sediments and determining corrosion control parameters of steel in anae- robic mud.

The effect of surface roughness on nucleation and growth of metastable pitting on amorphous NiCrFeSiB alloy was studied using potentiostatic and potentiodynamic polarization tests.Nucleation of metastable pits on the alloy was significantly facilitated by rougher surface.

Rougher surface also promoted the growth of metastable pits, and lead to a wider distribution of the growth rates.

The corrosion behavior of electroless NiP deposits on the carbon steel in deaerated 35%NaOH solution have been studied by potentiodynamic polarization method, electrochemical impedance spectroscopy(EIS) technique and atomic force microscopy(AFM). The results showed that the anodic polarization behavior of the NiP deposit with high P content were very similar to that of low P deposit, but the corrosion current densities of the high P deposit were much lower than that of the low P deposit. The low phosphorus deposit exhibited a roundedmound structure surrounded by fairly deep crevices and the size of the nodules varied from 0105 m, the depth of the crevices was about 1020 nm. The high phosphorus deposit exhibited a more uniform and smoother surface structure, the size of the nodules was smaller and the depth of the crevices was approximately 25 nm.
