Surface modification of polymer-coated steel sheet by plasma treatment
In order to control the rate of corrosion, plasma gas discharge was applied to modify the surface of a polymer coated-steel sheet to be hydrophobic. Since the corrosion resistance of steel is strongly related to water permeation, the surface hydrophobicity of materials was introduced by CF3H plasma exposure. The corrosion property before and after the plasma treatment was investigated in a slat spray tester of 3.5% NaCl fog at 35degreesC. The results showed that the CF3H plasma-induced polymer exhibited significant retardation of corrosion.
