| 摘要： | Zinc and aluminum have been used as steel coatings since the early 1900s, with early application of thermally sprayed metal coatings (TSMCs) to bridge structures in the 1930s. TSMCs have been used widely in the European bridge industry, the U.S. Navy, and on offshore oil exploration drill platforms for quite some time. TSMCs of zinc, aluminum, and their alloys can offer substantial advantages when compared with other coatings typically used to protect steel pilings. Organic coatings can fail prematurely as a result of corrosion progression from coating defects. Transportation, handling, installation, or simple long-term material deterioration may cause these defects. TSMCs offer advantages in generally higher mechanical damage resistance, low self-corrosion rates, and the ability to provide steel corrosion control via cathodic protection at coating defects. The objective of this research was to develop a guide for highway agency personnel on the selection and use of TSMCs on highway pilings that would be suitable as an AASHTO reference. |
