AI Technical Summary
Existing anti-corrosion coatings for marine photovoltaic steel structures suffer from poor dispersibility, weak adhesion, and insufficient weather resistance in marine environments. In particular, their stability decreases with long-term use under high salinity and ultraviolet radiation.
The composition of a permeable layer and an anti-corrosion coating is adopted. The permeable layer absorbs carbon, nitrogen and oxygen elements through gas permeation treatment to form a dense layer. The anti-corrosion coating incorporates silanized composite carbon material, which is chemically bonded to the fluorine-modified coating to form a dense barrier layer, thereby enhancing the interfacial bonding and hydrophobicity.
It significantly improves the corrosion resistance, weather resistance and mechanical strength of the anti-corrosion coating, enhances its resistance to mechanical wear and ultraviolet aging, and improves the corrosion resistance of steel structures.
