| THE EFFECT OF MARINE ENVIRONMENT FACTORS ON THE CORROSION RATES OF STEELS |
|
|
| Abstract: |
| The corrosion of steels in sea water is a result of combined effects of various changing environment factors. Data were obtained about the sea water temperature, dissolved oxygen, salinity and pH value of the testing sea area through long term and systematic measurements-Data were obtained simultanuously about the corrosion tests of two steels, which were proceeded in twelve terms. The results showed that under the combined effect of the marine environment factors the corrosion rate of the steels increased with the rise of seawater temp erature. The dissolved oxygen showed little effect on the corrosion rate of the steels. How ever, a combined effect of these two factors might exist. Changes of pH value and salinity of the sea water can be neglected. In addition, the difference of season when the tests started rendered differents results of one year corrosion tests of A3 steel. This is an important factor concerning short term tests. |
