英文摘要	Plasma electrolytic oxidation (PEO) of AA1060 aluminium was carried out in aluminate electrolytes to develop corrosion-resistant coatings. Different concentrations (0, 2 and 4 g/L) of a SiO2 nanoparticle (n-SiO2) additive and different treatment times of 15 min and 30 min were employed in this investigation. The PEO coatings were characterized by using a scanning electron microscopy (SEM) equipped with energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). The corrosion resistances of each coating was evaluated by electrochemical methods. Results showed that n-SiO2 hindered the formation of the alpha-Al2O3 phase and promoted the generation of the gamma-Al2O3 and mullite phases. The addition fo n-SiO(2)in the electrolytes could shorten the breakdown time of PEO, enhance the breakdown voltage, reduce the number of pores in the electrolyte/coating (E/C) interface and enlarge the internal cavity. The coating formed after 15 min in a NaAlO2 solution containing 4 g/L n-SiO2 additive showed the best corrosion resistance, exhibiting the lowest corrosion current density of similar to 8.7 x10(-10) A/cm(2).
