Application of Long-range Protection Heat-sprayed Metal Compound Coats in Ocean Atmosphere

In this article, the corrosion states of the heat spayed Al, Zn and Al-Zn compound organic coats on steel plate in the Xiamen ocean atmosphere are investigated and the result indicates that the corrosin resistance of Al-Zn coats is superior than that of Al and Zn coats. Based on the investigation,a long range composite protection plan applied to a large engineering project is proposed.
