| Abstract: |
| In this paper, the atmospheric corrosion protection status of common municipal metal structures in 17 cities of Shandong province was investigated, and the reasons for the failure of some protection methods were analyzed. Geographical location, temperature, pollutants, stress, welding and other factors affect the corrosion protection directly or indirectly. The deposition of chloride ions and the adsorption of air pollutants are the most important factors accelerating the failure of atmospheric corrosion protection methods. The reasonable selection of protection methods and the design of protection schemes are very important for prolonging the service life of metal structures. Good protective measures were taken for some facilities, but they failed for neglecting of weak portions. Among them, the corrosion protection of bolts is a common problem that did not receive proper attention. |
