Accelerated cyclic corrosion tests were carried out on four types of metallic coating systems, zinc hot dip galvanizing, zinc-aluminum alloy thermal spraying, low-temperature zinc-aluminum alloy thermal spraying, and aluminum thermal spraying. X-scribe lines reaching underlying steel substrate and uncoated region of 20×70mm were made on steel plates coated by the coating systems. The coated test specimens were exposed into the S6-cycle corrosion environments specified in Japanese Industrial Standards (JIS) K5621 for 100, 200 and 300 days, respectively. The variation of the surface conditions and thickness of the metal coating films were examined at the testing times of 0, 100, 200, and 300 days. After removing corrosion productions on the surface of the test specimens, the surface conditions and the thickness loss were also examined. From the test results, relative corrosion performance of the metallic coating systems was discussed.}, pages = {795--800}, title = {Corrosion Performance of Metallic Coating Systems for Steel Bridges}, year = {2005} }
