Investigation on the Anti-Corrosion Layer of the Power Transmission Steel Structures

Article Preview

Abstract:

The power transmission steel structures are used in the outdoor and the durability will be decreased due to the various corrosions, so the structures usually coated the anti-corrosion layers such as hot-dip coating, zinc-rich coating or thermal spray zinc coating. The anti-corrosion layers on three power transmission steel structures in Henan province, China were investigated by the corrosion morphology and the residual coating thickness. The results indicated that the corrosion degree of the bolts is higher than that of the steels, and there are local corrosions occurred on the surface of the steels due to the plating leakage or clash.
