containing 50 g/L sulfuric acid and 10 g/L adipic acid. The thickness of the formed anodic oxidation film was approximately 7.13 μm. The interpore distance and the diameters of the major pores in the porous layer of the film were within the approximate ranges of 10–20 nm and 5–10 nm, respectively. Insoluble eutectic Si particles strongly influenced the morphology of the anodic oxidation films. The anodic......

with deionized water, and then anodized in a ammonium adipate bath at 90 ℃ under a voltage of 100 V. A anodic film was thus formed. The foils were then immersed in an iodine/methanol solution at 40 ℃ for 10 h... and the corresponding anodic polarization curves in the same solution were measured. It is found that there is a dependence of llim on the potential difference, ?φ, between the pitting potential, φpit......

The crystal type......
aspects: anodic potential, anodic corrosion rate, morphology and composition of the anodic oxidation film, purity and morphology of cathodic product. The results show that the porous anode can... lower than that of Pb-Ag plate anode, which can significantly decrease the energy consumption. Besides, the anodic oxidation film of porous anode changes from loose, powdery form into denser, flatter......
