Aluminum Alloy Surface

In order to improve the corrosion resistance property of the aluminum alloy surface, a simple chemical immersion method was developed for fabricating the super-hydrophobic surface on aluminum alloy. After treating the chemical etched surface using low surface energy material stearic-acid, the aluminum alloy surface exhibits a super-hydrophobic property with water contact angle of 154° and contact angle hysteresis of 7°. The surface morphology was inspected with scanning electron microscope, and it was found that the surface was configured in a labyrinth structure with convexity and caves of micro-nanostructure; this hierarchical micro-nanostructure plays an important role in the formation of the super-hydrophobic surface. The effects of the etching time and the etchant (potassium permanganate solution) concentration on the super-hydrophobic surface were investigated, and the optimum technical conditions are that etching the aluminum alloy in 0.1mol/L potassium permanganate solution concentration for 3 h. At the same time, we also studied the wettability of the aluminum alloy super-hydrophobic surface. The results showed that the super-hydrophobic aluminum alloy has good stability, corrosion resistance property and self-cleaning.

Excellent Corrosion Resistance

In this paper, Pd ions doped cerium conversion coating (CeCC/Pd) was deposited on AA2219-T87 aluminum alloy by electroplating. The microstructure and composition of the coating were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS). Corrosion behavior of AA2219-T87 aluminum alloy with the coating was investigated in 3.5wt.% NaCl solution at the room temperature. XRD and XPS results indicate the existence of cerium-oxide and palladium-oxide in the CeCC/Pd. Polarization curves show that the CeCC/Pd exhibits excellent corrosion resistance. The corrosion current density of the CeCC/Pd decreases by two orders of magnitude compared with the CeCC. The improvement of corrosion resistance would be attributed to the small grain size, good compactness and adhesive strength of the composite coatings.
