CORROSION RESISTANCE OF NANOCOMPOSITE COATINGS ON CARBON STEEL BY USING EIS MEASUREMENT
纳米复合涂层对碳钢防腐性能的交流阻抗评定

Corrosion perfomance of three kind of coatings,i.e. the PPS based coatings filled with microsized-(normal coating) or nanosized pigments(nanocomposite) and the later one plus a post treatment with a surfactant of fluorine(hydrophobic nanocomposite coating),was investigated by means of electrochemical impedance spectroscopy(EIS) mesearement.The results show that the nanocomposite coating showed better corrosion resistance than the normal ones.However,the hydrophobic nanocomposite coatings showed the best corrosion resistance,which may be owed to the beneficial effect induced by the treatment with surfactant of fluorine.
