| Abstract: |
| According to the deep sea environment test data obtained from USA and the shallow seawater data from our country, TA2 and SS316 will not behave galvanic corrosion tendency in the deep sea. However, during the practical use, SS316 appears the severe galvanic corrosion. In practical and simulated deep sea environment, there is no galvanic corrosion between the static TA2 and SS316. However, if there is abrasion between the two metals to damage the passive film on SS316, the galvanic corrosion will occur. SS316 will work as the anode to accelerate the corrosion. |
