Title: Structure and Performance of Zirconia Conversion Film on AA6061 Aluminum Alloy
Abstract: The zirconia conversion film was deposited on AA6061 aluminum alloy via fluorozirconate treatment.The morphology and composition of the zirconia conversion film were investigated by scanning electron microscopy and energy dispersive spectrometer,and its corrosion resistance was tested by electrochemical and neutral salt spray tests.The results show that the zirconia conversion film is colorless and consists mainly of the Zr and Al oxides.The zirconia conversion film has a higher corrosion resistance.The coating system of the zirconia conversion film painted epoxy resin paints or polyurethane paints have passed 1 500 hrs salt spray test,and the zirconia conversion film can be used as the backing on aluminum alloy surface for subsequent painting.
