Abstract
In marine, aviation and railway transportation, dirt, corrosion, and wear lead to rapid failure of equipment, and organic coating is the main protective means. Epoxy (EP) coating is a widely used film-forming material in organic coating. We report a new modification method — fluorine modified silicon carbide (F–SiC) modified EP coating. The hydrophobicity, wear resistance and corrosion resistance of the EP coating were improved by grafting fluorinated organic compound (F–SiC) onto the surface of silicon carbide particles and adding it to the EP coating. When the content of F–SiC is 3 wt.%, compared with the EP coating without F–SiC, the contact angle between 3 wt.% F–SiC EP coating and water increases by 63%, and the friction coefficient decreases by 73%. The corrosion resistance of 3 wt.% F–SiC EP coating is about three orders of magnitude higher than that of the EP coating soaked for six days.
