A long effect anticorrosion system of high speed boat's steel hull--of Spray Zinc-aluminum pseudo-alloy system

摘要

The steel yield pre one Chinese people of 2007 own to near to 200% of the world level. Be therefore carry on bearing the corrosion protection steel structure's life, become more and more outstanding mission. Now, spray Zinc-Aluminum pseudo-alloy layer, spray with the strong power, twice breezes recently, get high contain aluminum in the back of the layer. It has a long effect proved by the long period NSS (Neutral spray salt fog test) method. It can be attain the long effect protection of 80 years. There is a presupposition by American scholar:"Aluminum oxidizes and zinc oxidizes fill up in the eyes of the network made by Al2O3, and formed an anticorrosion layer. " This paper used examination to proved the total content of aluminum and the two kinds oxides attain 70%. Thereby this paper proved the presupposition by American scholar. Spray Zinc-Aluminum pseudo-alloy layer to protect the steel hull of the high-speed boat, will be a good method.
