This paper deseribed the types and main corrosion causes of large-scale steel structure, and introduced the applicationof zinc thermal-spraying and its coupling coating in large-scale steel structure.

This paper combined the anti-corrosion design of Wuhan Qintai Lake s steel structure and on-site inspec- tion corrosion results after one year service,it is found that Hot-dip galvanized and Thermal Spraying Zinc may provide su- perior effective protection than paint in the water or wet environmental conditions.

Compared to bitumen painting,zinc coating can pro.

Ductile cast iron pipe samples coated with zinc coatings of different unit area weight (90,130 g/m2 and 200 g/m2) were immersed in 5 g/L NaCl solution, and the evolution of the electrochemical potential of the samples was measured periodically using electrochemical two -electrodes technique.

Anti-erosion hot spraying zinc construction administration and quality control for gates of Silong HPP;

The thesis analysis several factors which affect the stain resistance by comparing the stain resistanceof arc spraying zinc and powder penetrating zinc workpieces in different medias.

The corrosion protection of the hydraulic metal structure is a difficult topic in its production and operation Combined with the practice of some engineering buildings,the corrosion mechanism and the corrosion protection method are introduced,and the work process of the spraying zinc method is discussed in detai
