| 1 | Thick and Dense Anodic Oxide Layers Formed on Aluminum in Sulphuric Acid Bath显示文摘Thick and dense oxide layers were obtained on aluminium in sulphuric acid electrolyte. For this purpose, the methodology of experimental design was used. A three-variables Doehlert design (bath temperature, anodic current density, sulphuric acid concentration), was achieved. In order to maximize the growth rate and the density of the anodic oxide layer, optimum path study was conducted. Under the determined optimal anodizing conditions (5.7℃, 3 A·dm -2 , C sul =140 g·L -1 ), the estimated response values were 0.86 μm·min -1 and 3.12 g·cm -2 for growth rate and density, respectively. The morphology of optimum layer was examined by scanning electron microscopy (SEM). The compactness of the optimum anodic layer can be correlated with its morphology revealed by SEM observations. | W. Bensalah M. Feki M. Wery H.F.

| 7 | Mechanical and Abrasive Wear Properties of Anodic Oxide Layers Formed on Aluminium显示文摘Aluminium oxide coatings were formed on aluminium substrates in oxalic acid-sulphuric acid bath.Abrasion tests of the obtained anodic layers were carried out on a pin-on-disc machine in accordance with the ISO/DP 825 specifications.The Vickers microhardness,D(HV0.2),and the abrasion weight loss,Wa(mg) were measured.Influence of oxalic acid concentration(Cox),bath temperature(T) and anodic current density(J) on D and Wa has been examined,and the sulphuric acid concentration(Csul) was maintained at 160 g·L-1.It was found that high microhardness and abrasive wear resistance of oxide layers were produced under low temperatures and high current densities with the addition of oxalic acid.The morphology and the composition of the anodic oxide layer were examined by scanning electron microscopy(SEM),atomic force microscopy(AFM),optical microscopy and glow-discharge optical emission spectroscopy(GDOES).It was found that the chemistry of the anodizing electrolyte,temperature,and current density are the controlling factors of the mechanical properties of the anodic oxide layer. | W.
