| Summary | Taiwan belongs to the subtropical zone which has island climate characteristics of high tem perature, high humidity, and high salinity where in the m etal components corrode easily. For this reason, establish ing a database of local underwater corrosion environment al data and corrosion factor s is required in order to facilitate the basis for futur e corrosion protection design and maintenance management of structures. The major work items of this research include: 1. completing the 2 year term underwater corrosion test of metal materials in each port; 2. establishing a database of underwater corrosi on; 3. analyzing and comparing survey data; 4. e stablish ing a database of underwater corrosion rate for metal materials in Taiwan Corrosion Environment Information System. After two years of exposure of the metal materials in each port area, the analysis r esults showed that the corrosion rate in different locations for the splash zone corrosion rate of carbon steel ranged from 309 to 743 (µm / yr). The maximum corrosion rate occurred at the Taipei Port, and the corrosion rate of low carbon steel was between 323 and 729 (µm / yr), the maximum corrosion rate occurred at the Port of Keelung. The corrosion rate of carbon steel in the tidal zone was between 170 and 425 (µm / yr), the maximum corrosion rate occur red in Taipei Port, the corrosion rate of low carbon steel was between 182 and 586 (µm / yr), and the maximum corrosion rate occurred in Keelung Port. The corrosion rate of carbon steel in water zone range d from 160 to 334 (µm / yr). The maximum corrosion rate occur red at the Port of Keelung. The corrosion rate of low carbon steel range d from 118 to 502 (µm / yr). The maximum corrosion rate occur red at the Port of Keelung as well As for the analysis of underwater corrosion rate of different metal materials t he second year test results showed that the maxim um corrosion rate of the carbon steel metal (SM490) in the splash zone occurred at Taipei Port , which was 743 (µm / yr) and the tidal zone 425 (µm / occurred at Taipei Port. T he water zone 334 (µm / yr) occurred at Keelung Port. In the second year, the maximum corrosion rate of low carbon steel in the splash zone occur red at Taipei Port , which was 729 (µm / yr), tidal zone 586 (µm / yr) was at Keelung Port, and the water zone 502 (µm / yr) occur red at Keelung Port. Benefits a nd Applications: It enable s the engineering units to understand the trend of corrosive environment where structures are located, provid ing Taiwan International Port s Corporation, Ltd., Civil Engineering Anti corrosion Society Industrial Development Bureau of Ministry of Economic Aff airs , Formosa Plastics Group , China Steel and Engineering Consult ant Compan ies with reference applications for industry, government, and academia. |
