Zirconium-based conversion coating(ZrCC)with chromium-free was successfully prepared on aluminum alloy 6061(AA6061).The effects of various pretreatments including the treatment time of alkaline washing,the concentration of nitric acid and the addition of hydrofluoric acid on the corrosion resistance of ZrCC have been studied in the present work.
