| 内容記述 | This paper discusses durability of four types of steel bridge metallic coating systems based on combined cyclic corrosion tests. Metallic coating systems tested in this study are zinc hot dip galvanized (ZHDG) coating, zinc-aluminum alloy (ZAA) coating, zinc-aluminum pseudoalloy (ZAPA) coating, and aluminum alloy (AA) coating. The combined cyclic corrosion test followed S6 cycle conditions specified in Japanese Industrial Standard K5621. In addition to the standard S6 cycle, S6 cycle conditions with an acid rain spray period in place of a salt water spray period were also used to evaluate the effect of acid rain on durability of metallic coating systems. Steel plates with metallic coating systems were placed in a cyclic corrosion test chamber under these two different cyclic conditions for 300 days. Durability of metallic coating systems was evaluated by coating thickness loss and remaining coating area in this study, and differences in deterioration characteristics between the salt water spray and acid rain spray combined cyclic corrosion tests were investigated. The coating thickness loss was greater in the acid rain cyclic corrosion test except for ZAPA specimens, implying that ZHDG, ZAA, and AA coatings should be used with a great care when they may be exposed to acid rain. In both salt water spray and acid rain spray cyclic corrosion tests, AA specimens showed the best durability of the four metallic coatings. | |||||
