TL;DR: The mechanical properties and corrosion resistance of 316-L stainless steel fabricated using the Laser Engineered Net Shaping (LENS) technique have been studied in this paper, and the results prove that the microstructure of the SS316L fabricated using LENS is heterogeneous; its impact on the mechanical properties is visible.
Journal ArticleDOI
Structural features of self-organized nanopore arrays formed by anodization of aluminum in oxalic acid at relatively high temperatures
TL;DR: In this article, anodic aluminum oxide (AAO2O) templates were fabricated in 0.3 M oxalic acid under the anodizing potential range of 30-65 V at a relatively high electrolyte temperature ranging from 20 to 30 V.
Journal ArticleDOI
Synthesis of anodic aluminum oxide (AAO) at relatively high temperatures. Study of the influence of anodization conditions on the alumina structural features
TL;DR: In this article, a systematic analysis of the anodization condition influence on the nanoporous alumina structural features was done and the results showed that the pore diameter increases with potential, temperature and time of anodisation, while the interpore distance is influenced solely by the potential.
Journal ArticleDOI
Fabrication of high quality anodic aluminum oxide (AAO) on low purity aluminum—A comparative study with the AAO produced on high purity aluminum
TL;DR: In this paper, the quality, arrangement, composition, and regularity of nanoporous AAO formed on the low-purity (AA1050) and highpurity aluminum during two-step anodization in a mixture of sulfuric acid solution (0.3 m), water and glycol (3:2, v/v), at various voltages (15, 20, 25, 30, 35 ) and at temperature of −1 ǫ c, are investigated.
Journal ArticleDOI
The effect of anodizing temperature on structural features and hexagonal arrangement of nanopores in alumina synthesized by two-step anodizing in oxalic acid
TL;DR: In this article, the influence of anodizing temperature on the structural features and pore arrangement of nanoporous anodic aluminum oxide (AAO) layers was investigated, and it was found that the better nanopore order in AAO is observed, the higher temperature is applied.
