ANTI-CORROSION PROPERTIES OF POLYANILINE CONTAINING COATINGS ON Mg-Li ALLOY
|
Abstract:
Polyaniline-SiO2 composites(PANI-SiO2)were prepared by means of chemical oxidation of aniline with ammonium persulphate in sulfosalicylic acid medium.The PANI-SiO2 was characterized by FTIR,XRD and SEM methods.A coating consisted of PANI-SiO2 and epoxy resin(EP)was prepared on Mg-Li alloy,and its anti-corrosion properties were investigated by open circuit potential and electrochemical impedance spectroscopy.The results indicated that the PANI-SiO2 containing coating showed good anti-corrosion property in 3....
